Explosions were reported in Moscow overnight on June 26, prompting airport closures, with Russia's Defense Ministry claiming 50 Ukrainian drones were downed across the country.

Moscow Mayor Sergey Sobyanin said emergency services were at the sites where two drones were downed.

According to the Shot Telegram channel, which appears to be close to Russian security forces, debris from a downed drone struck a residential building.

"Alarms went off everywhere," a local resident told the channel.

Ukraine's military regularly strikes military targets deep within Russia in an attempt to diminish Moscow's fighting power as it continues its war against Ukraine.

Russia's Defense Ministry later claimed 50 Ukrainian drones had been downed across the country, two of which were "flying towards Moscow."

The Kyiv Independent could not independently verify these claims.

Kaluga airport and Moscow's Vnukovo airport had flight restrictions imposed amid the drone attack, Artyom Korenyako, a spokesperson for Russia's state aviation agency Rosaviatsia, said early on June 26.

"The airport is temporarily not accepting or sending flights. Aircraft crews, air traffic controllers, and airport services must take all necessary measures to ensure flight safety," he said.

The restrictions were later lifted.

Putin insists the Russian economy is fine, but Kremlin officials say otherwise

In a rare public sign that all is not well in Russia, two high-ranking Moscow officials last week issued separate warnings about the state of the country’s economy. Russian Central Bank Governor Elvira Nabiullina and Economy Minister Maxim Reshetnikov both highlighted that amid the Kremlin’s full-scale war against Ukraine, the tools Moscow once relied on to maintain wartime growth are nearly exhausted.

Ukrainian drones have forced at least 217 temporary airport closures across Russia since Jan. 1, independent Russian outlet Novaya Gazeta Europe reported on May 14, citing data from Russia's state aviation agency Rosaviatsia.

The figure already surpassed the combined total for all of 2023 and 2024, underscoring Kyiv's growing ability to put pressure on Russia, even in areas far from the border with Ukraine.

According to Serhii Bratchuk, spokesperson for the Ukrainian Defense Army's Southern Division, the surge in disruptions reflects a strategic shift in Ukraine's drone campaign.

"Moscow is the biggest aviation hub in the Russian Federation — flights go everywhere, not only across Russia, but worldwide," he told the Kyiv Independent last month.

"This is about the potential disintegration of Russian regions and the weakening of internal control."

Ukraine has also had remarkable success using first person view (FPV) drones — on June 1, Ukraine launched a game-changing drone attack on four key Russian military airfields, damaging 41 planes, including heavy bombers and rare A-50 spy planes.

Kyiv claimed it disabled 34% of Russia's strategic bomber fleet in what is seen as one of the most daring operations during Russia's full-scale war.

United States Secretary of State Marco Rubio surprised NATO allies this week with conflicting messages on Russia sanctions, delivering a tougher stance in private than in his public remarks, Politico reported on June 25.

Rubio met with NATO foreign ministers on June 25 during a private dinner at the alliance's annual summit. According to sources who spoke with Politico, Rubio acknowledged that Russia was the main obstacle preventing peace talks to end the war in Ukraine.

He reportedly said the U.S. Senate would likely consider new sanctions legislation after completing work on President Donald Trump's spending bill.

However, just hours later, Rubio softened his position on Russia during an exclusive interview with Politico, calling for a more cautious approach.

"If we did what everybody here wants us to do, and that is come in and crush them with more sanctions, we probably lose our ability to talk to them about the ceasefire and then who's talking to them?" Rubio said.

He also added that Trump would know the "time and place" to change course.

When asked about the apparent shift in tone, a senior U.S. official insisted Rubio's messaging has remained consistent in conversations with allies.

"The secretary has been very consistent in meeting and calls with his counterparts on three key point," the official said.

"One is that the president believes strongly that the only way this war ends is through negotiations; second, as soon as the U.S. imposes new sanctions on Russia the opportunity for the U.S. to be involved in those negotiations closes; and third, that the Senate, in America anyway, is an independent body that at some point is going to move on those sanctions,."

At the NATO dinner, Rubio reportedly faced criticism from Polish Foreign Minister Radoslaw Sikorski, who claimed that Russian President Vladimir Putin was disrespecting Trump by violating the ceasefire.

It has been more than 100 days since Ukraine agreed to a U.S.-backed complete ceasefire, while Russia continues to reject it.

Sikorski also reportedly denounced Moscow's repeated attacks on Kyiv and other Ukrainian cities, which have intensified in recent weeks, saying such strikes "should not come for free" — implying that the U.S. and Europe should do more to support Ukraine.

Meanwhile, Rubio has delivered different messages in public and behind closed doors. Despite the shifting rhetoric, Baltic and Nordic countries reportedly view him as a pragmatic ally within the Trump administration — one who has a realistic understanding of the threats posed by Russia and China, according to a second European official cited by POLITICO.

Ukraine and the Council of Europe signed a historic agreement on June 25 to establish a Special Tribunal for the Crime of Aggression, marking a major step toward holding Russia's leadership accountable for launching the full-scale invasion in 2022.

The agreement was signed by President Volodymyr Zelensky and Council of Europe Secretary General Alain Berset during a ceremony in Strasbourg, France – following more than three years of diplomatic efforts and deliberation.

Speaking at the Parliamentary Assembly of the Council of Europe (PACE), Zelensky thanked the assembly and underscored the importance of justice.

"Everyone responsible for this war must be held to account," he said. "Every war criminal must face justice – including Putin... the crime of aggression must be recorded, judged, and punished."

Zelensky also praised PACE for its "real leadership" in taking a stand against Russia and developing the tribunal.

"It was here in this assembly, that the first call for such a tribunal was made," Zelensky said. "The idea was born here – and now it’s gaining real support from partner countries in Europe and beyond."

The Special Tribunal will be established within the framework of the Council of Europe and will have the mandate to prosecute senior Russian leaders for the crime of aggression – defined as the decision to use armed force against another state, in violation of the United Nations Charter.

President Zelensky has long advocated for the creation of the tribunal, emphasizing the need to bring Russian President Vladimir Putin and other senior officials to justice. Ukrainian prosecutors have documented thousands of war crimes committed by Russian forces, including attacks on civilians, cultural landmarks, medical facilities, and reports of torture and forced deportations.

The tribunal is intended to close a key legal gap in existing international accountability mechanisms.

While the International Criminal Court (ICC) has jurisdiction to investigate war crimes, crimes against humanity, and genocide in Ukraine – and has already issued arrest warrants for Putin and Maria Lvova-Belova, the Russian official overseeing the forced deportation of Ukrainian children to Russia – it cannot examine the crime of aggression due to jurisdictional constraints.

The new tribunal will complement the ICC's efforts by specifically targeting high-level officials responsible for starting the war – such as Putin and his inner circle.

In addition to the special tribunal, the Council of Europe’s Ukraine-related work  includes the Register of Damage – an initiative that has already received more than 34,000 claims detailing losses and harms resulting from Russia's full-scale invasion.

The establishment of the register, and now the special tribunal, are important steps to ensure justice for Ukraine and its people.

Zelensky, Trump hold talks on NATO summit sidelines

“We covered all the truly important issues,” President Volodymyr Zelensky said. “We discussed how to achieve a ceasefire and a real peace. We spoke about how to protect our people. We appreciate the attention and the readiness to help bring peace closer.”

Speaking at a NATO press conference in The Hague on June 25, U.S. President Donald Trump said it was possible Russia could target other countries beside Ukraine.

When asked whether Russian President Vladimir Putin has territorial ambitions beyond Ukraine, Trump replied, "it's possible."

"I know one thing: He (Putin) would like to settle (the war). He'd like to get out of this thing. It's a mess for him," he added.

Foreign officials and EU diplomats have increasingly called for the preparation for a potential full-scale conflict between NATO and Russia.

Trump's remarks came days after President Volodymyr Zelensky said that Ukraine's intelligence has proof that Russia is preparing new military operations in Europe and just a week after Putin declared "all of Ukraine is ours."

During The Hague summit, NATO Secretary General Mark Rutte called on alliance members to be realistic about the threats posed by Russia and China.

While Trump appeared to downplay concerns about Putin’s threat, he later said that the Russian leader "really has to end that war" against Ukraine. During his speech, he also referred to Russia’s all-out war as a "crisis," a term used by some Russian allies but criticized by Kyiv.

"I consider him (Putin) a person I think is misguided," Trump said.

The U.S. leader said his June 25 meeting with Zelensky, which preceded the briefing, "couldn’t have been nicer."

"I think it’s a great time to end it (war). I’m going to speak to Vladimir Putin, see if we can get it ended," Trump said. "He (Zelensky) is fighting a brave battle, it's a tough battle."

Separately, Trump acknowledged that Ukraine wants to receive Patriot missiles, saying that the U.S. is going to see "if we can make some available."

In recent weeks, Russia has intensified drone and missile attacks on Kyiv and other Ukrainian cities, killing and injuring hundreds of civilians.

Despite Kyiv's appeals, Trump has dismissed the request, accusing Zelensky of "always looking to purchase missiles" and falsely blaming Ukraine for provoking the war.

The front-line city of Kostiantynivka in Ukraine's Donetsk Oblast is facing a looming "humanitarian catastrophe" as ongoing Russian strikes destroy critical infrastructure and leave thousands without basic services, Governor Vadym Filashkin said on June 25.

Kostiantynivka, in eastern Donetsk Oblast, lies just 10 to 15 kilometers (6 to 9 miles) from several areas currently occupied by Russian forces, according to battlefield mapping site DeepState. The city has come under intensified attack in recent months as Moscow pushes westward beyond its gains around other nearby towns.

According to Filashkin, nearly half the city is without electricity due to shelling, and 1,900 households in the Santurynivka district have no access to gas, with restoration currently impossible. Water is supplied just once a day from 5 p.m. to 8 p.m., meeting only 20–25% of the city's needs.

Drone strikes have halted all city bus operations, while the suburban route to Druzhkivka, a nearby town, is operating on a limited basis, Filashkin said.

Yevhen Alkhimov, press officer of Ukraine's 28th Mechanized Brigade, which is fighting near Kostiantynivka, told the Kyiv Independent that "the greatest danger at the moment comes from first person view (FPV) drones, including fiber optic models."

"The enemy is trying to control all logistics and communication routes," he said, adding: "The Russians’ goal right now is not so much to destroy the city as it is to make it unsuitable for defense by controlling all the roads."

Alkhimov said Russian forces were deliberately targeting vehicles including civilian buses.

"They are trying to fully control all movement in the city using their drones," he said.

Authorities have installed seven large water tanks and 11 smaller containers throughout the city, in addition to 12 wells, six of which are equipped with filtration systems. Five "Points of Invincibility," Ukraine's emergency support hubs, are operational, with two more on standby.

Despite the risks, emergency crews, doctors, utility workers, and local officials continue to work in the city.

"Civilians still remain in the city, and life is becoming more and more difficult for them," Alkhimov said.

"There are fewer people left, the curfew is now longer, but nonetheless, people are still there, and it is truly very dangerous for them to stay in the city."

Filashkin urged those still in the city to evacuate.

Russia has intensified its offensive in eastern Ukraine while insisting that any peace negotiations must recognize its claimed annexation of four Ukrainian oblasts and Crimea. Russian forces do not fully control any of the four regions it seeks to claim.

Ukraine has ruled out ceding its territory as part of any peace agreement.

Ukraine's security service (SBU) has charged in absentia a former defense engineer with treason, accusing him of helping Russia target Ukrainian cities by developing navigation systems for cruise and ballistic missiles, the SBU said on June 25.

According to the agency, Oleh Borsuk, a 61-year-old Ukrainian national, fled to Russia in 2009 after resigning from a defense plant in Cherkasy Oblast. He later became deputy general director of Moscow-based design bureau "Navis," a major player in Russia's military-industrial complex.

Borsuk allegedly oversaw the development and modernization of satellite guidance systems (GPS/GLONASS) used in Russian missiles. In 2023 alone, under his leadership, nearly 3,200 satellite navigation units were produced, including those for Iskander tactical missile systems, the SBU said.

These systems are also used in missiles like the Kh-101, Kh-59, and Kalibr — weapons frequently deployed in Russian airstrikes against Ukrainian civilian infrastructure.

The deadliest attacks include the July 8, 2024, strike on the Okhmatdyt children hospital in Kyiv, which killed two adults, including a doctor, and injured more than 50 people, including children. The hospital was hit by a Kh-101 cruise missile in accordance with a programmed route.

Another devastating strike occurred on June 17, when a massive missile and drone assault on Kyiv killed 30 people and injured 172 others. One of the deadliest impacts was a direct hit on a residential building by a Russian Kh-101 cruise missile, which caused the complete collapse of an entire section of the nine-story residential building.

According to a spokesperson for Ukraine's Air Force Yurii Ihnat, the building was struck by a Kh-101 missile.

The SBU has charged Borsuk in absentia under Ukraine's Criminal Code for treason committed under martial law.

"Since the perpetrator is hiding in the territory of the Russian Federation, comprehensive measures are underway to bring him to justice for crimes against our state," the SBU said.

U.S. Secretary of State Marco Rubio said in an interview with Politico on June 25 that U.S. President Donald Trump will resist European pressure to escalate sanctions on Russia, arguing that doing so could close the door to potential peace negotiations with Moscow.

Speaking with Politico on the sidelines of the NATO summit in The Hague, Rubio said Trump wants to keep open a diplomatic channel with Russian President Vladimir Putin, despite growing frustration from European leaders and President Volodymyr Zelensky over Russia's refusal to agree to a ceasefire.

"If we did what everybody here wants us to do, and that is come in and crush them with more sanctions, we probably lose our ability to talk to them about the ceasefire and then who's talking to them?" Rubio said.

Rubio acknowledged that Russia appears committed to pursuing its objectives by force.

"Our sense of it is that the Russians are going to try to achieve on the battlefield what they've demanded at the negotiating table, which is certain territories, administrative lines, and the like," he said. "We think it’s going to be a lot harder for them to achieve that than they think it's going to be."

Rubio added that Trump "will know the right time and place" for additional sanctions, but emphasized that imposing them too soon could signal that the U.S. has given up on a negotiated resolution.

Previously, Trump said he had refrained from imposing new sanctions on Russia because he believed a peace deal with Moscow might be within reach, warning he did not want to jeopardize negotiations by acting prematurely.

Speaking after two rounds of peace talks in Istanbul between Moscow and Kyiv that led to no ceasefire, Trump on June 5 declined to say when additional sanctions on Russia might be imposed, only noting there is a deadline "in (his) brain."

"If he (Trump) does it, you're almost admitting that this is not going to be negotiated anytime soon," he said. "We're going to continue to engage. In the sense that if there's an opportunity for us to make a difference and get them to the table, we're going to take it."

Zelensky and several European leaders are expected to ask Trump during meetings at the summit to increase economic pressure on Moscow.  

It has been more than 100 days, since Ukraine agreed to a U.S.-backed complete ceasefire, while Russia continues to reject it. Moscow continues pushing maximalist demands while intensifying attacks across Ukrainian cities.

Russian attacks across Ukraine killed at least 23 people and injured more than 300 others over the past 24 hours, local officials said on June 25.

According to the Ukrainian Air Force, Russian forces launched 71 Shahed-type attack drones and decoys from multiple directions, including Bryansk, Millerovo, Kursk, and occupied Crimea. Ukraine's air defenses destroyed 52 of them.

In Dnipropetrovsk Oblast, a ballistic missile attack killed at least 20 people, 18 in Dnipro and two in the Samarskyi district, in one of the deadliest single attacks in recent weeks, governor Serhii Lysak said.

Nearly 300 people were injured, and extensive damage was reported to high-rise buildings, houses, dormitories, cars, schools, hospitals, administrative offices, and a passenger train. Drone strikes overnight also hit Nikopol and caused a fire in Synelnykove district.

In Kharkiv Oblast, nine people were injured in strikes on Kharkiv city, Kupiansk, and surrounding villages, according to Governor Oleh Syniehubov. Russian forces used a mix of weaponry, including air-launched rockets, glide bombs, and various drones. Civilian infrastructure was damaged, including residential buildings, houses, and an industrial hangar.

In Zaporizhzhia Oblast, five peope were injured in attacks across the Zaporizhzhia, Vasylivka, and Polohy districts, Governor Ivan Fedorov reported. Russian forces conducted four missile strikes on Zaporizhzhia and eight airstrikes on several towns. Around 300 drones, and over 150 artillery strikes were recorded across 13 settlements.

In Donetsk Oblast, three civilians were killed in Pokrovsk, Zoloti Prudy, and Novoiavlenka, Governor Vadym Filashkin said. 11 more were wounded in the region over the past day.

Russia has launched over 28,000 Shahed drones at Ukraine since 2022, with nearly 10% fired in June alone, Zelensky says

Speaking on June 24, Volodymyr Zelensky stressed that Russia would never have been able to carry out such drone attacks without support from Iran, and Ukraine, in turn, could not have intercepted most of the drones without the help of its international partners.

A key military-industrial site in the Russian city of Taganrog linked to Moscow's production of combat drones and electronic warfare systems was damaged overnight, a Ukrainian official said on June 25, amid Russian reports of Ukrainian drones targeting the area.

"Something unknown flew into the Atlant-Aero plant in Taganrog," Andrii Kovalenko, head of the counter-disinformation center at Ukraine's National Security and Defense Council  said.

"This is an important node in the Russian military-industrial complex, specializing in components for combat drones and control systems."

Kovalenko said the plant is involved in the production of "Orion" drones, electronic warfare complexes, and digital integration systems for strike FPV (first person view) drones and loitering munitions.

Russian authorities reported a wave of overnight Ukrainian drone attacks across multiple regions, including Rostov, which borders eastern Ukraine. Russia's Defense Ministry said its forces shot down 40 Ukrainian drones over several areas, including the Crimean Peninsula and seven over the Rostov region.

Rostov Governor Yuri Slyusar said on Telegram that while there were no casualties, the strikes allegedly caused a fire at a sports complex and damaged a high school and two residential buildings in Taganrog. In nearby Azov, a grain warehouse and industrial facility were hit, he added, without providing further detail.

The Kyiv Independent could not verify the claims.

Throughout Russia's full-scale invasion, Ukraine and Russia have extensively invested in drone technology, revolutionizing the way wars are fought.

Ukraine has ramped up its domestic drone production and long-range strike capabilities as it seeks to weaken Russian military infrastructure deep behind enemy lines. Earlier in June, Ukrainian drones targeted long-range Russian bombers in an operation dubbed "Spiderweb."

Russia has escalated its missile and drone attacks on Ukrainian cities, launching hundreds of drones during overnight assaults. Since February 2022, Moscow has launched 28,743 Shahed-type drones at Ukraine

Speaking at the NATO Defense Industry Forum in The Hague on June 24, President Volodymyr Zelensky said Ukraine can produce over 8 million drones of various types each year. He called for an increased investment from the allies to reach that potential.
