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. Almost immediately, Russian President Vladimir Putin on June 20 dismissed the concerns, clai

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.

Washington will "see" whether it can supply Kyiv with additional missiles for its Patriot air defense systems, U.S. President Donald Trump said during the NATO summit in The Hague on June 25 as Russia escalates its air strikes against Ukraine.

"They (Ukraine) do want to have the anti missiles, as they call them, the Patriots, and we're going to see if we can make some available," Trump said.

"They are very hard to get. We need them too. We are supplying them for Israel, and they are very effective."

After the meeting with Trump earlier in the day, Zelensky said that the two discussed the purchase of American air defense systems to shield Ukrainian cities and critical infrastructure.

In recent weeks, Moscow has intensified its drones and missiles strikes. As NATO leaders gathered for the summit, Russia launched an attack on the city of Dnipro, killing at least 19 people and injuring more than 300 others.

"Ukraine is ready to buy this equipment and support American weapons manufacturers. Europe can help. We also discussed the potential for co-production of drones. We can strengthen each other," Zelensky added.

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

The Patriot is a high-precision, U.S.-made surface-to-air missile platform capable of intercepting aircraft, cruise missiles, and ballistic threats. Zelensky has repeatedly said Ukraine needs at least seven more systems to defend its most at-risk regions.

In early June, he confirmed that Trump's administration diverted 20,000 anti-drone missiles originally intended for Ukraine to American forces in the Middle East.

Since the start of Russia’s full-scale invasion, Moscow has launched 28,743 Shahed-type drones at Ukraine — with 2,736, or roughly 9.5%, fired in June 2025 alone, Zelensky said.

‘It’s possible’ — Trump on Putin’s territorial ambitions beyond Ukraine

“I consider him (Russian President Vladimir Putin) a person I think is misguided,” U.S. President Donald Trump said speaking at a NATO press conference in The Hague on June 25.

Since the start of Russia’s full-scale invasion, Moscow has launched 28,743 Shahed-type drones at Ukraine — with 2,736, or roughly 9.5%, fired in June 2025 alone, President Volodymyr Zelensky said during a speech to the Dutch Parliament in The Hague.

Speaking on June 24, he 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.

Zelensky called for accountability and emphasized that rules must apply to all — including the Kremlin: "Putin pretends not to understand the rules that shape the modern world. And here, in The Hague, I want to say this very clearly to him: There is a rule — do not kill. There is a rule — do not treat people like beasts. There is a rule — do not destroy cities and villages. There is a rule — do not sponsor terror. There is a rule — do not steal children. And if you break these rules, you will be held accountable."

According to Zelensky, these principles — though difficult for Russia to grasp — form the foundation of international norms, from the UN Charter to Europe’s shared vision of life.

To achieve lasting peace, Zelensky outlined two key strategic priorities. First, he called for maximum isolation of Russia which includes full political isolation, comprehensive sanctions, and the termination of any cooperation that allows Russia to survive and continue waging war.

"Every loophole that allows them to keep going must be closed. We need a strong 18th EU sanctions package. We need tough, painful sanctions on Russian oil. Every reduction in Russia’s oil revenue helps bring peace closer," he said.

Zelensky argued that the most effective step would be imposing a $30-per-barrel price cap on Russian oil exports.

“The world must reach this threshold — not just to help stop Russia’s war against us, but to prevent any future military operations that Russia might launch against Europe and the Alliance,” he said. “Military plans must become prohibitively expensive for Russia. We must fully block their tanker fleet and cut them off from international banking. That’s what works.”

Second priority, according to Zelensky, is the need for stability in defense support. "Russia must see that Ukraine will not be left alone, and that Europe will not back down."

Norway will invest $400 million in Ukraine's defense industry to support drone and air defense missile production, President Volodymyr Zelensky said in his nightly address on June 22.

The announcement followed a visit to Ukraine by Norwegian Defense Minister Tore Onshuus Sandvik.

"Today, Norway’s Minister of Defense visited Ukraine. A decision has been reached to invest $400 million in our production – new funding, primarily for drones," Zelensky said.

Zelensky added that the two countries are also working together to establish joint air defense production inside Ukraine.

"We are working together to create all the necessary conditions to produce air defense systems in Ukraine — jointly with partners, jointly with Norway," Zelensky said.

He added that Norway's largest defense company – Kongsberg Defence & Aerospace – has already opened an office in Ukraine as part of the cooperation.

"We are expediting all processes to the maximum extent," Zelensky said.

On X, Norway's defense ministry confirmed that Kongsberg has signed agreement with a major Ukrainian company to jointly develop and produce missiles for air defense systems in Ukraine.

The collaboration will focus on producing missiles for the National Advanced Surface-to-Air Missile System, or NASAMS.

"The Norwegian NASAMS system saves lives in Ukraine every day, and is crucial in protecting critical infrastructure. That is why it is important for the Norwegian Government to finance this development of cheaper missiles for the NASAMS system in Ukraine," said Minister Sandvik.

The announcement marks deepening ties between Kyiv and Oslo as Ukraine seeks to expand its domestic defense industry amid Russia’s ongoing full-scale invasion and reduced military aid from the United States.

Ukraine is downing approximately 82% of Russian Shahed-type drones during Russian massive aerial attacks on Ukrainian cities despite a serious shortage of surface-to-air missiles, Commander-in-Chief Oleksandr Syrskyi told journalists on June 21.

Ukraine needs to have many times more surface-to-air missiles and anti-aircraft missile systems to ensure reliable defense of cities and critical infrastructure facilities, Syrskyi said at a briefing attended by the Kyiv Independent.

Russian attacks against Ukraine have surged in May and June as Moscow has launched several record-breaking mass strikes against Kyiv and other cities. The latest attack on June 17, primarily targeting the capital, killed 30 people and injured over 170.

"Since we have to save anti-aircraft guided missiles, mobile fire groups are the priority for defending from the Shaheds," Syrskyi said.

Despite Russia's changing tactics of massive air attacks, mobile fire groups account for the largest share of destroyed drones. The fire groups' effectiveness is up to 40%, according to Syrskyi.

Aviation is used almost every night to repel Russian air attacks, featuring the Defense Forces' helicopter crews and fighter aircraft of the Air Force, which includes U.S.-made F-16 and French Mirage-2000 aircraft.

"One promising area in countering Shaheds is the use of light aircraft," Syrskyi said, adding that "there are new projects thanks to financial and material assistance from our foreign partners."

"We are receiving modern light aircraft, which have modern weapons and navigation, which will increase the effectiveness in countering Russian strike drones."

Syrskyi stressed that "cooperation with partners, primarily Canadian ones, enables us to obtain modern surveillance and targeting systems that enhance the combat capabilities of our helicopters."

Regular Air Force reports show that the majority of Russian drones are intercepted during overnight attacks, some by air defenses and others by electronic warfare systems. However, these reports do not always clarify how many of the intercepted drones were actual attack drones and which were only decoys launched to overwhelm air defenses.

Ukraine works to develop other means of protection against Russian air raids in the non-front-line oblasts as it scales up the use of interceptor drones.

Syrskyi said that over five types of interceptor drones have been cleared for use in the army, and new units are being formed and taught to operate them. Some of these Air Force units have already downed dozens of Russian Shaheds, according to Syrskyi.

The effective use of interceptor drones is hindered by the lack of tactical radar systems in Ukraine, such as Israel-made radars by RADA Electronic Industries and their analogues.

Syrskyi said the Ukrainian army needs hundreds of tactical radar systems instead of the few currently in service for radar reconnaissance, which is key to the use of interceptor drones.

Ukraine's military intelligence (HUR) destroyed three Russian air defense systems using drones in the occupied Zaporizhzhia Oblast on June 14, HUR says.

"Strike drone masters of the Department of Active Operations of the HUR of the Ukrainian defense ministry discovered and destroyed expensive air defense systems of the Russian invaders in the temporarily occupied territory of the Zaporizhzhia region," HUR reported in a post to Telegram.

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

A Russian Buk-M3, a Pantsyr S1, and a 9S19 Imbir radar from the S-300V air defense system were destroyed in the Ukrainian drone attack.

"The video shows a stunning maneuver of a Ukrainian drone dodging a Muscovite anti-aircraft missile, as well as episodes of successful fire strikes," HUR's statement said.

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.

Ukraine's military intelligence agency was behind explosions near Desantnaya Bay in Russia's far eastern Vladivostok on May 30, which reportedly damaged military personnel and equipment, a source in HUR told the Kyiv Independent.

Efforts are underway to rapidly expand Ukraine's ability to counter Russian drone attacks, Commander-in-Chief of Ukraine's Armed Forces, Oleksandr Syrskyi, said on June 14.

In a statement shared on Telegram, Syrskyi said he held a meeting focused on strengthening defenses against Russian strike drones, particularly Iranian-designed Shahed drones used by Russian forces to target Ukrainian cities.

"Task number one is scaling up the systems that already work effectively," Syrskyi said. "First and foremost, that means increasing the number of drone interceptors."

Russia has been escalating drone attacks against Ukraine over the past weeks, launching record 400-500 UAVs (unmanned aerial vehicles) per night.

Syrskyi emphasized the need for a comprehensive approach that incorporates all available capabilities. "(Russia) is constantly modifying the characteristics of its Shaheds and changing their tactics," he said.

Ukrainian officials discussed ways to improve early detection of incoming drones and ensure their timely destruction. Syrskyi said he had set clear priorities and tasked military leaders accordingly.

Russia has repeatedly targeted Ukrainian cities with waves of attack drones, often striking energy infrastructure and residential buildings overnight. Ukraine's defense forces use a mix of electronic warfare, air defense systems, and drone-on-drone interception to repel the assaults.

Drones have become one of the defining tools of the full-scale war, used extensively by both Ukraine and Russia for surveillance, long-range strikes, and tactical battlefield advantage. In recent weeks, Russia has intensified its drone and missile attacks on Ukrainian cities and infrastructure.

Earlier on June 9, Ukraine's Air Force said it intercepted 479 drones and missiles during one of the largest attacks since the start of the war. Russia launched 499 weapons overnight, including 479 Shahed-type drones and multiple ballistic and cruise missiles.

NATO plans to enhance its missile defense systems on its eastern flank in response to a growing threat from Russia, Bloomberg reported on June 12, citing its undisclosed sources.

For the first time, member states of NATO are reportedly considering combining the alliance's ballistic missile shield with other integrated missile defense assets. The talks are taking place behind closed doors and involve sensitive deliberations, Bloomberg reported, citing its sources.

Moscow has long opposed NATO's missile defense infrastructure, particularly the U.S.-built interceptors deployed in Poland and Romania, states neighboring Ukraine. The alliance has previously said those systems are intended to counter potential long-range threats from Iran, not Russia.

The so-called "NATO expansion to the east" is one of the key narratives used by Russian propaganda to justify its large-scale war against Ukraine.

The proposed integration of ballistic missile defense with NATO's broader air and missile defense network would address threats from any direction in the future. This shift suggests the effort would increasingly be focused on deterring Russian capabilities, according to Bloomberg's sources.

The move comes as NATO ramps up its defense posture more than three years after Russia launched its full-scale invasion of Ukraine. The alliance recently agreed on the most ambitious new weapons targets since the Cold War.

NATO Secretary General Mark Rutte called on alliance members to make a "quantum leap" in defense investment in response to the enduring threat from Russia. Speaking at Chatham House in London, Rutte urged allies to increase air and missile defense by 400%.

Talks on integrating the systems may wrap up ahead of the NATO summit in The Hague on June 24–25, but could continue afterward, the sources said. Ukraine is invited to attend the summit. It remains unclear whether the initiative will still officially cite Iran as a threat or move fully toward addressing Russia.

The effort is part of a broader strategy to reinforce NATO's eastern flank, but some officials have raised concerns about how it might affect peace efforts in Ukraine and whether the United States will fully support the integration, Bloomberg reported.

Previously, U.S. President Donald Trump echoed Russian claims that Kyiv provoked the invasion by pursuing its NATO ambitions.

Earlier, Bloomberg reported that NATO is deploying a new satellite surveillance system aimed at monitoring military activity in Ukraine and along the alliance's eastern borders. The system, known as Smart Indication and Warning Broad Area Detection (SINBAD), will use AI-powered analysis to scan large areas and detect potential threats with unprecedented frequency.
