Russian forces launched a drone attack on Kharkiv overnight on June 24, injuring three people and damaging civilian infrastructure, Mayor Ihor Terekhov said.
The first explosions were reported around 2:00 a.m. local time, with three civilian injuries confirmed by 4:00 a.m., according to local officials.
Seven Iranian-made Shahed drones were launched at the city, three of which struck their targets, Terekhov said.
The strikes damaged a civilian enterprise in the Saltivka district and residential buildings in Nemyshlianskyi.
Emergency services responded to the affected sites.
In recent weeks, Moscow has been intensifying attacks against Kharkiv – Ukraine's second-largest city – which sits just over 20 kilometers (15 miles) from the Russian border.
A Russian drone attack against the city overnight on June 12 injured at least 15 people, including children.
Serbian President Aleksandar Vucic announced on June 23 that Serbia has halted all arms exports, citing national security and economic interests. He denied that the move was a response to mounting criticism over allegations that Serbian munitions have ended up in Ukraine.
Speaking after a meeting with senior military officials, Vucic said that Serbia is only sending ammunition to its own barracks and all exports are suspended, in line with Serbia's best interests.
Shortly after the announcement, Serbia's Defense Ministry issued a statement confirming the suspension of all arms and military equipment exports.
Vucic's decisions comes amid increasing criticism – particularly following claims that Serbian ammunition has been supplied to Ukraine.
In May 2025, Russia’s Foreign Intelligence Service (SVR) accused Belgrade of supplying weapons to Kyiv, despite Serbia's friendly ties with Moscow and declared neutrality in Russia's invasion.
According to a 2024 investigation by the Financial Times, Serbian ammunition has made its way to Ukraine through intermediaries, although Belgrade maintains it does not directly arm either side.
Since Russia’s full-scale invasion of Ukraine in 2022, Serbia has attempted to navigate a delicate diplomatic path between Moscow and the West.
In his most recent balancing act, Vucic refused to sign a declaration condemning the invasion – so as not to "betray Russia" – while simultaneously pledging to support Ukraine's reconstruction.
Russian forces launched a drone attack on Sumy Oblast overnight on June 24, killing three people, including an 8-year-old boy, and injuring six others, local officials reported.
The strike targeted a settlement near Verkhnia Syrovatka around midnight local time, Governor Oleh Hryhorov said on Telegram. The victims included an adult man and woman, and the child.
As of 7:00 a.m. local time, six people – including three children – have been reported injured. All have been hospitalized and are receiving medical care.
The attack damaged about 30 residential buildings and four cars, and sparked a large-scale fire. Police investigators, rescue workers, and medics are responding at the scene.
Sumy Oblast, which borders Russia, has faced intensified assaults in recent weeks amid a broader Russian offensive along Ukraine's northeastern border.
Since March, Russian forces have reportedly captured around 200 square kilometers in the region, prompting evacuations from over 200 settlements.
Ukrainian forces, however, have been reportedly driving Russian troops back amid the continued cross-border attacks.
Ukrainian President Volodymyr Zelensky met with U.K. Prime Minister Keir Starmer at Downing Street on June 23, ahead of the NATO summit in The Hague.
Zelensky had earlier paid a visit to King Charles III at Windsor Castle before joining Starmer to discuss continued British support for Ukraine’s defense.
During a joint visit to a U.K. military training site for Ukrainian personnel, Starmer said he and Zelensky held "an excellent bilateral meeting" and had agreed to an "industrial military co-production agreement." He described the deal as "a massive step forward in the contribution that we can continue to make." Zelensky added the agreement "will be very strong and will transform both nations," though specific details were not disclosed.
Addressing Ukrainian troops, Starmer said it was "really humbling" to witness their "level of professionalism, commitment and bravery." Around 58,000 Ukrainian service members have been trained under the international program based in the U.K.
Zelensky thanked the U.K for its consistent backing since the start of Russia’s full-scale invasion in 2022. “We are very thankful to the UK... for such big support of Ukraine from the very beginning of this war,” he said. He noted that the UK-based training initiative has “strengthened our army” and enabled Ukraine to “survive and fight.”
The visit precedes the NATO summit in The Hague, where allies are set to unveil new defense spending targets. NATO Secretary General Mark Rutte said member states will aim to spend five percent of GDP on defense — a move he called “a quantum leap that is ambitious, historic and fundamental to securing our future.”
Under a compromise deal, members will commit to allocating at least 3.5 percent of GDP to core military expenditures and 1.5 percent to broader security areas such as cybersecurity and infrastructure.
Ukraine's Armed Forces struck the Atlas oil depot in Russia's Rostov Oblast overnight on June 23, the General Staff reported.
The attack ignited a fire at the site, with Ukrainian forces saying the strike had reached its intended target. The facility supplies fuel and lubricants to Russian military units.
Yuri Slyusar, the acting governor of Rostov Oblast, confirmed that a fire occurred at an industrial facility after the attack. He added that no one was injured.
The full extent of the damage is still being assessed, according to the military.
Located near the Azov Sea and bordering Ukraine, Rostov Oblast plays a crucial logistical role for Russia's war effort due to its proximity to front-line operations. The same depot was previously targeted in November 2024.
"The defense forces continue to take all measures to undermine the military and economic potential of the Russian occupiers and force the Russian Federation to stop its armed aggression against Ukraine," the General Staff said.
The strike is part of Ukraine's broader campaign aimed at disrupting Russian supply chains and degrading its capacity to sustain the full-scale invasion.
Fuel depots, rail infrastructure, and ammunition stockpiles inside Russia and occupied territories have increasingly become targets for long-range drone and missile strikes.
Iran launched multiple missiles at U.S. military bases in the Middle East, targeting sites in Qatar and Iraq, a day after the U.S. conducted air strikes on nuclear sites in Iran.
At least 10 missiles were reportedly fired at the Al Udeid Air Base in Qatar and at least one toward a base in Iraq, Axios reported, citing an Israeli source.
The U.S. Defense Department confirmed that Iran launched several short- and medium-range missiles at Al Udeid Air Base, the New York Times reported. According to the Pentagon, there have been no reports of American casualties.
President Donald Trump downplayed Iran's response to the recent U.S. strike on its nuclear facilities, describing Tehran’s retaliation as limited and largely ineffective. "There have been 14 missiles fired — 13 were knocked down, and 1 was 'set free,' because it was headed in a nonthreatening direction," Trump said in a statement on Truth Social. He emphasized that no Americans were harmed and that the damage was minimal.
Trump went on to say, "Most importantly, they’ve gotten it all out of their ‘system,’ and there will, hopefully, be no further HATE." Ending on a conciliatory note, Trump added that he would "enthusiastically encourage Israel" to pursue peace in the region.
Iranian President Masoud Pezeshkian wrote on X that his country "neither initiated the war nor wanted it, but we will not leave the aggression against the great Iran unanswered."
Iran's targeting of U.S. assets marks a dangerous widening of the conflict, raising fears of further destabilization in the region.
The missile strikes come in response to the June 21 U.S. air campaign that targeted three nuclear facilities in Iran — Fordow, Natanz, and Esfahan — as Washington joined Israel's military operation against Tehran's nuclear program.
The escalation follows Israel's June 13 attack that prompted Iran to retaliate with missile attacks on Tel Aviv and other cities, killing multiple civilians, including five Ukrainian citizens.
Iran is a key supplier of weapons to Russia, including Shahed-type drones and ballistic missiles used in attacks on Ukrainian cities. Israel, which hosts a significant Russian-speaking population, has not joined Western sanctions against Moscow.
On June 13, Kyiv expressed concern over the security situation in the Middle East, describing Tehran as a "source of problems" in the region and beyond.
Ukraine's state defense conglomerate Ukroboronprom and European aerospace giant Airbus have signed a trilateral cooperation memorandum at the Le Bourget International Air Show, the company announced on June 23.
The agreement launches initiatives to develop maintenance and repair capabilities for Airbus aircraft operating in Ukraine among specialists at Ukroboronprom's enterprises.
As part of the deal, Airbus will send representatives to Ukraine to train local specialists, who will then become certified instructors for aircraft maintenance.
"Trust in our defense industrial complex, particularly Ukroboronprom and its enterprises, is growing among global high-tech companies," said Oleh Hulyak, Ukroboronprom Director General, in a press release. "This proves we have chosen the right path for development and international cooperation."
Hulyak expects new partnerships with foreign partners in aviation and other areas of the company's work.
Ukroboronprom is a leading strategic manufacturer of weapons and military hardware in Ukraine. The association unites about 100 enterprises that develop and manufacture weapons, military equipment and ammunition, including missiles, drones, armored vehicles.
The company reported a consolidated net profit of Hr 1.31 billion ($31.5 million) for the previous year as its enterprises tripled production volumes in 2024 compared to 2023, with a 36% increase in contracts.
In 2024, Ukroboronprom was rankedfor the first time in history among the top 50 global defense companies by Defense News, according to Strategic Industries Minister Alexander Kamyshin.
Ukrainian Deputy Prime Minister Oleksii Chernyshov on June 23 was formally named a suspect in a high-profile illegal land grab case, becoming the highest-ranking official in Ukrainian history to face such charges while in office.
After reports and public speculation around Chernyshov's potential involvement, the National Anti-Corruption Bureau (NABU) released a statement announcing that he was the sixth suspect in a “large-scale” corruption scheme led by a property developer from Kyiv who illegally claimed a land plot to build a residential complex.
In a comment to the Kyiv Independent, Chernyshov denied the accusations against him. "I'm absolutely not involved in that (scheme) — that's clear," he said.
He also said he won't step down from his post. "I will stay in this position," Chernyshov told the Kyiv Independent.
Chernyshov, who heads the new National Unity Ministry in charge of returning refugees, is a close ally of President Volodymyr Zelensky. He raised eyebrows in Ukraine after leaving the country days before law enforcement revealed a massive corruption scheme and detained two of his former close associates — Maksym Horbatiuk and Vasyl Volodin.
According to the anti-corruption agency, during his time as communities and territories minister in 2020-2022, Chernyshov and his associates undervalued land plots by five times to benefit the developer, which Ukrainian media identified as Serhii Kopystyra, allegedly costing the state Hr 1 billion ($24 million).
In exchange, NABU says the developer gave kickbacks to Chernyshov and his accomplices with "significant" discounts on apartments in his existing buildings, totaling over Hr 14.5 million ($346,000). Ukrainian news site Ukrainska Pravda reports this took place between 2021-2022.
NABU and Ukraine's Specialized Anti-Corruption Prosecutor's Office (SAPO) seized the plot to prevent the scheme. Most of the illegally obtained apartments have been seized.
Chernyshov arrived back in the country on June 22 after suspicions mounted in Ukraine that he was on the run and avoiding detention.
"I was definitely on a business trip and I was not escaping out of Ukraine," Chernyshov told the Kyiv Independent. "The rumors of me not returning are nothing but manipulation. I came exactly once my trip was over. I had a very intensive trip in Europe."
Chernyshov claims he was targeted by a "smear campaign" but said he didn't know who could be behind it.
He also said that he came back on his own accord and denied that anyone had asked him to return.
The minister arrived at the NABU offices on June 23, after the agency summoned him to be charged. Upon leaving the bureau, Chernyshov wrote on Facebook that he had a “constructive chat” with detectives and will cooperate with the organization.
An investigation into Chernyshov and two of his associates took place last year after suspicions arose, according to Ukrainska Pravda, with the agency obtaining a warrant to search Chernyshov's home.
But sources in anti-corruption agencies told Ukrainska Pravda that the head of NABU, Semen Kryvonos, blocked police searches due to his close relationship with Chernyshov, who was his boss when Kryvonos headed the State Architecture Inspection, an agency that was subordinated to Chernyshov's former ministry.
Searches allegedly took place a few weeks ago, after a one-year delay, according to Ukrainska Pravda.
Chernyshov said that while he knows Kryvonos in a professional manner, the two are not in contact. He added that the allegations against Horbatiuk and Volodin look "quite serious" but that it was for law enforcement to decide if their detention is justified.
He was appointed head of state-owned energy giant Naftogaz in 2022 after the dissolution of the Communities and Territories Development Ministry. He became the national unity minister in December 2024, a ministry created from scratch.
Chernyshov is widely believed to have a personal friendship with Zelensky. According to a report by Ukrainska Pravda, he was among only a handful of guests invited to celebrate Zelensky's birthday during the Covid-19 pandemic in 2021 — and the only member of the Cabinet of Ministers in attendance.
"The key thing is that today NABU and SAPO have actually reached the immediate circle of the president's 'family,'" Olena Shcherban, deputy executive director at the Anti-Corruption Action Center (ANTAC), a Kyiv-based watchdog, told the Kyiv Independent.
The President's Office feels the threat from NABU and SAPO and will likely attack the two institutions in response to Chernyshov's notice of suspicion, rather than "saving" the minister, Shcherban added.
"I am sure we will see both attempts to make harmful changes to the law and personal attacks on the SAPO head (Oleksandr Klymenko)," she said.
U.S. President Donald Trump on June 23 called for urgent measures to prevent rising oil prices amid escalating tensions with Iran.
"Everyone, keep oil prices down. I'm watching," Trump wrote on Truth Social. "To the Department of Energy: Drill, baby, drill! And I mean now."
The post comes after global oil prices surged on June 13 following a series of Israeli air strikes on Iranian nuclear facilities. The escalation sparked fears of broader conflict in the energy-rich Middle East, home to critical oil shipping routes.
The surge in oil prices risks undermining Western attempts to curb Russia's war funding, as the Kremlin relies heavily on oil revenues to sustain its invasion of Ukraine. President Volodymyr Zelensky has warned that a price surge could further embolden the Kremlin.
On June 21, the U.S. joined Israel in conducting airstrikes that targeted three nuclear facilities in Iran — Fordow, Natanz, and Esfahan. The operation triggered a strong response from Tehran, which threatened to block the Strait of Hormuz, a key global oil transit route.
U.S. Vice President JD Vance responded on June 22 that any Iranian attempt to shut the strategic waterway would "destroy their own economy." The strait is a vital chokepoint for global energy supplies, with nearly a fifth of the world's oil passing through it daily.
Amid the turmoil, the EU has reportedly postponed plans to tighten the $60-per-barrel price cap on Russian crude, originally imposed in December 2022. The mechanism restricts Western firms from shipping or insuring Russian oil sold above that threshold.
The Russian Finance Ministry has relied heavily on energy revenues to sustain defense spending, which hit record highs this year.
Ukrainian state grid operator Ukrenergo's supervisory board has appointed Vitaliy Zaichenko, the company's current chief dispatcher, as its new head, Ukrainian media reported on June 23.
The company has been under temporary management of Oleksiy Brekht while the supervisory board struggled with prolonged disputes over the selection process.
Ukrenergo, which operates Ukraine's electricity transmission system and is a member of the European electricity grid network (ENTSO-E), plays a critical role in the country's energy security, especially during wartime when Russian attacks have repeatedly targeted energy infrastructure.
Zaichenko beat out two other finalists: Oleksiy Brekht, the interim head of Ukrenergo, and Ivan Yuryk, former acting head of Ukrainian Railways.
The supervisory board's June 4 attempt to elect a new CEO failed amid conflict with the Energy Ministry, which changed appointment rules without consulting the Energy Community Secretariat, drawing criticism from European partners.
The new rules complicated the selection process by requiring five out of seven supervisory board votes instead of the previous four needed to elect a chairman.
According to Ukrainian MP Max Khlapuk, the European Bank for Reconstruction and Development (EBRD) threatened to block 141 million euros ($152 million) in funding and demand early repayment of 533 million euros ($574 million) already received over the rule changes.
Former Ukrenergo CEO Volodymyr Kudrytskyi was dismissed on Sept.2, 2024, after President Volodymyr Zelensky called for his resignation over alleged failures to protect substations from Russian missiles and drones.
Kudrytskyi disputed this account, saying he initiated the supervisory board meeting himself, though he did not reveal the reasons for his dismissal.
Following Kudrytskyi's dismissal, supervisory board chairman Daniel Dobbeni and member Peder Andersen resigned early, citing political pressure in personnel decisions.
Ukraine's largest private energy company DTEK and British clean energy group Octopus Energy have launched a program to install rooftop solar panels and battery storage systems at Ukrainian businesses and public institutions, DTEK said in a press release on June 23.
The program, called RISE (Resilient Independent Solar Energy), was announced at Octopus Energy's Tech Summit in London and aims to raise 100 million euros ($115 million) to finance 100 energy projects over three years, helping stabilize the grid, lower electricity costs and protect customers from outages, the company said.
DTEK’s facilities have been repeatedly targeted since the start of Russia’s full-scale invasion as Moscow sought to cripple Ukraine's energy infrastructure. The company was forced to shut down its gas production facilities in Poltava Oblast in March.
"About 70% of Ukraine's thermal generation capacity has been damaged, destroyed or seized since the full-scale invasion," said DTEK CEO Maksym Timchenko in the press release.
“This has created not only an urgent need to rebuild but also an opportunity to accelerate the shift to a decentralized, renewable energy system,” he added.
The alternative energy systems will be installed by D.Solutions, DTEK's business unit operating under the Yasno retail brand.
Installed equipment will run on Octopus Energy's AI-powered Kraken operating system, enabling businesses to optimize energy use in real time, reduce consumption during peak hours and sell surplus electricity back to the grid.
"They (DTEK) are rebuilding at pace and pioneering a decentralized, smart energy system powered by homegrown renewables," said Greg Jackson, Octopus Energy Group founder and CEO.
According to DTEK, Ukraine's commercial and industrial energy market has an untapped potential of 300 megawatts annually, valued at 200 million euros ($229 million). DTEK's Yasno brand serves over 60,000 business customers and can generate projects worth 30 million euros per year.
DTEK previously announced plans to build one of Europe's largest energy storage facilities with six installations across the country, totaling 200 megawatts to power 600,000 households. The company secured a $72 million loan from three Ukrainian banks.
Russian President Vladimir Putin in 2023 authorized the ordering of at least two attempts to assassinate Ukrainian journalist Dmytro Gordon, Security Service of Ukraine (SBU) head Vasyl Maliuk told media on June 23, RBC-Ukraine reports.
Gordon is a prominent journalist and media personality popular in both Ukraine and other post-Soviet countries, known for his sharp criticism of Russian aggression. His YouTube channel has 4.5 million subscribers.
"Gordon triggers Russians. He has a large audience in Russia and in the (Russian) occupied territories (of Ukraine)," Maliuk said. "There are two networks that worked on Gordon that we can speak (publicly) about."
According to the SBU, the first network was led by a former lawmaker from the now-banned pro-Russian Party of Regions, originally from Poltava Oblast. The agency did not name the lawmaker.
The former MP was allegedly tasked by Russia's Federal Security Service (FSB) with coordinating surveillance and preparations for a strike that would kill Gordon.
"The plan was to use a homemade explosive device or coordinate a missile or a drone strike — but only if Gordon's presence in the targeted house was confirmed," Maliuk said.
The SBU had already been investigating the ex-lawmaker for involvement in a separate railway bombing case in Poltava Oblast when the assassination plot was uncovered. The group was arrested before executing the plan.
The second assassination team, Maliuk said, was a criminal group from Dagestan working secretly for the FSB under the cover of being fugitives from Russian law enforcement.
"They sent this individual here long before the full-scale war. He carried out FSB tasks all the time — very professionally, very covertly," Maliuk said.
The group monitored Gordon's movements and residence, planning to assassinate him either with a short-barreled weapon if he was alone, or with a rifle and follow-up pistol shot if accompanied by a bodyguard.
The SBU detained the group, and its leader confessed to preparing the hit on Moscow's orders. He said he had been promised $400,000 for the killing.
Gordon, who has become a high-profile figure on Ukraine's information front, regularly uses his platform to expose Russian disinformation and advocate for Ukrainian sovereignty.
A lion has attacked collaborator Oleg Zubkov at the Taigan Safari Park he founded in Russian-occupied Crimea, the Crimean Wind Telegram channel reported on June 22.
Zubkov is a businessman who renounced his Ukrainian citizenship and began cooperating with the Russian authorities following Moscow's illegal annexation of Crimea in 2014
He also smuggled animals from zoos in the partially occupied Zaporizhzhia and Kherson oblasts after the full-scale invasion of Ukraine in 2022.
During an evening feeding, Zubkov was attacked by a lion which tore his trachea, neck, and chest muscles with its claws. He managed to leave the lion's enclosure but then lost consciousness.
As a result of the attack, Zubkov lost a significant amount of blood and was transported by helicopter to a hospital in Simferopol, Crimea.
Zubkov regained consciousness on June 23 after surgery, and his condition is described as stable.
This is not the first time lions at the Taigan Safari Park have attacked its staff. In 2024, three lions killed Leokadia Perevalova while she was cleaning an enclosure. Perevalova had worked at the park for 17 years.
Three people were killed and at least 12 others injured after a Russian ballistic missile strike hit the city of Bilhorod-Dnistrovskyi in Odesa Oblast on June 23, Governor Oleh Kiper reported.
The attack targeted a local educational institution, destroying the building and leaving several people, including members of the teaching staff, possibly trapped under the rubble. No children were present at the time due to summer holidays, Kiper said.
As of 4:00 p.m. local time, three of the wounded were reported in serious condition, while the others — including two teenagers — were being treated for moderate injuries. The Air Force reported tracking two high-speed ballistic targets heading toward the city shortly before the strike.
Later in the day, Kiper reported that a 60-year-old woman died of her wounds at the hospital. Eight victims remained hospitalized as of 9:00 p.m. local time, while the rest were receiving outpatient care.
Bilhorod-Dnistrovskyi, a historic Black Sea city known for its Akkerman Fortress, lies near the mouth of the Dniester River.
Under international humanitarian law, the deliberate targeting of civilian infrastructure such as schools is forbidden and may constitute a war crime. Russia has repeatedly struck non-military sites throughout its full-scale invasion.
Earlier the same day, Russia launched another mass missile and drone attack on Kyiv, killing at least eight people and injuring 33 others, including four children, according to city officials.
Ukraine has returned the remains of three Russians who were handed over to Kyiv as part of an exchange of fallen soldiers' bodies, Interior Minister Ihor Klymenko told Interfax Ukraine on June 23.
Ukraine has said the practice of passing off the bodies of Russian soldiers as Ukrainian is part of an attempt to obscure the scale of its military losses from the Russian public, and at least 20 such incidents have been recorded during recent repatriations conducted under the Istanbul agreements.
Russia did not comment on the discovery made by the Ukrainian side, while Klymenko said during a press conference on June 23 that it could be done to "sow chaos" during the identification of the soldiers' bodies.
Personal badges, chevrons, documents, military uniforms elements, and footwear typical of the Russian Armed Forces were found during the bodies examination transferred by Russia to Ukraine, Ukraine's Interior Ministry said.
According to Klymenko, the bodies were transferred to Russia after confirmation that they belong to Russians. The other 17 bodies have not yet been handed over to Moscow, as examinations continues.
"We are waiting for the DNA of relatives. Therefore, we want the relatives (of Russians) to submit their DNA so that we can confirm," Klymenko told Interfax Ukraine. "I gave an order to prohibit the release of these bodies to the Russians until there is a 100% confirmation."
The Interior Ministry's experts conduct up to 10,000 examinations per month to identify individuals, and one fragment of remains can be examined up to five times, Klymenko said.
"The bodies of our heroes come back extremely mutilated. There are objective reasons for this, such as an ongoing war and widespread use of weapons. At the same time, we have recorded cases when the remains of one person were returned during different stages of repatriation, which complicates our work," Klymenko said.
The June 2 negotiations in Istanbul resulted in the most expansive prisoner and body exchange agreement of the full-scale war, although no ceasefire was reached.
Ukraine received a total of 6,057 bodies of its fallen soldiers as part of the phased exchange. Russia, according to Kremlin aide and negotiator Vladimir Medinsky, took back 78.
Explaining the difference between the two numbers, President Volodymyr Zelensky on June 20 said that the bodies of the vast majority of Russian soldiers currently killed on the battlefield remain in Russian hands.
"They were advancing, and their dead remained in the territory where they were," he said.
Russia accused Kyiv on June 7 of rejecting a proposed body return, publishing footage allegedly showing Ukrainian corpses stored in refrigeration units. Ukraine dismissed the claims, saying the footage was filmed on Russian territory, not at a designated handover site.
Kyiv has consistently called for an "all-for-all" exchange of prisoners of war, but Moscow has so far refused to agree to a comprehensive swap.
President Volodymyr Zelensky arrived in the U.K. on June 23 to conduct several meetings with "a primary goal" of deepening defense cooperation, presidential spokesperson Serhii Nykyforov said in comments reported by Ukrinform.
Zelensky's visit comes just a few hours after yet another Russian attack on Kyiv, which killed at least seven and injured almost 30 people. A residential buliding was partially destroyed in a direct ballistic missile hit.
In the U.K., Zelensky is to meet with King Charles III, British Prime Minister Keir Starmer, as well as with the speakers of both houses of parliament, Lindsay Hoyle and John McFall, according to Nykyforov.
Zelensky is also scheduled to meet with Ukrainian military personnel undergoing training in the U.K. and representatives of think tanks.
This year, the U.K. has allocated 4.5 billion pounds ($5.8 billion) for military assistance to Ukraine, marking its largest annual commitment so far.
London remains one of Kyiv's most steadfast military partners, providing long-range missiles, armored vehicles, training, and political support against Russian aggression.
Russian President Vladimir Putin has condemned U.S. strikes on Iran as "completely unprovoked aggression," more than three years into his completely unprovoked full-scale invasion of Ukraine.
Putin made the comments at the Kremlin during a meeting with Iran's Foreign Minister Abbas Araghchi on June 23, after U.S. President Donald Trump's announcement of successful air strikes on three nuclear facilities in Iran, Fordow, Natanz, and Esfahan, conducted in coordination with Israel over the weekend.
"The completely unprovoked aggression against Iran has no basis and no justification," Putin said, adding that Russia "is making efforts to provide assistance to the Iranian people."
Since Russia launched its full-scale invasion of Ukraine, Moscow has killed tens of thousands of Ukrainian civilians, and the true extent of the death toll is simply not known.
Russia's full-scale invasion of Ukraine was a clear and direct violation of both international law and the UN Charter.
Earlier on June 23, President Volodymyr Zelensky on highlighted Russia's hypocrisy for describing U.S. strikes on Iran as "grossly violating international law" just hours before launching yet another deadly mass missile and drone strike on Ukraine.
"After the strikes on Iran's nuclear facilities, there was an uproar from Moscow," Zelensky said.
"The Russian leadership demonstratively condemned the 'missile and bomb' actions. Today, Moscow is silent — after its own army launched a cynical attack using Russian-Iranian 'Shaheds' and missiles on civilian infrastructure in Kyiv and other cities."
Moscow on June 22 condemned the recent U.S. strikes against Iranian nuclear facilities.
"The irresponsible decision to subject the territory of a sovereign state to missile and bomb strikes, no matter what arguments are used, is grossly violating international law, the U.N. Charter, and the resolutions of the U.N. Security Council," the Russian Foreign Ministry said in a statement.
Overnight on June 23 a devastating Russian missile and drone strike on Kyiv killed at least 7 people and injured dozens more, including children.
The attack was one of the largest air assaults on the capital this year, with 368 aerial weapons launched, including 159 Iranian-made Shahed drones and 16 missiles, according to Ukraine's Air Force.
Russia has deepened military and political ties with Tehran since and Iran has supplied Moscow with thousands of Shahed-type attack drones used in routine strikes on Ukrainian cities, as well as short-range ballistic missiles.
Russia and Iran have cooperated to develop their own nuclear programs as both countries face Western sanctions. Russia supplied Iran with the Middle East's first nuclear power plant despite objections from the West.
Russia has lost around 1,012,500 troops in Ukraine since the beginning of its full-scale invasion on Feb. 24, 2022, the General Staff of Ukraine's Armed Forces reported on June 23.
The number includes 1,010 casualties Russian forces suffered just over the past day.
According to the report, Russia has also lost 10,965 tanks, 22,872 armored fighting vehicles, 52,861 vehicles and fuel tanks, 29,490 artillery systems, 1,423 multiple launch rocket systems, 1,188 air defense systems, 416 airplanes, 337 helicopters, 41,717 drones, 28 ships and boats, and one submarine.

Air defenses intercepted most, but not all. The attack hit six locations directly, causing destruction in 25 separate sites across Kyiv and the wider region.
Governor of Kyiv Oblast Tymur Tkachenko reported 6 people were killed, with 25 other injured in Kyiv alone, including four children.
In his remarks, Zelensky also warned of a growing alliance between Russia, Iran, and North Korea — a "coalition of killers," he said, and urged countries near these regimes to consider whether they can defend themselves if such a bloc continues to spread terror.
"Each country neighboring Russia, Iran, and North Korea should ask whether their own defenses are enough if this axis of evil preserves and remains unchecked," he said.
Zelensky, speaking ahead of meetings with British officials during his visit to the U.K., said he would push for stronger collective air defense and tougher sanctions on Russia.
Zelensky's comments came just a day after Ukraine's Foreign Ministry called for the dismantling of Iran's nuclear program following U.S. air strikes on Iranian nuclear sites.
"Iran is complicit in the crime of aggression against Ukraine," the ministry said in a June 22 statement. "The Iranian regime is providing military assistance to Russia, including the supply of UAVs and technologies that Russia consistently uses to kill people and destroy critical infrastructure."
The statement followed U.S. President Donald Trump's announcement of successful air strikes on three nuclear facilities in Iran, Fordow, Natanz, and Esfahan, conducted in coordination with Israel.
