Russia attacked the Ukrainian capital Kyiv with drones and missiles early on Thursday, officials ‌said, damaging several buildings, including one which partially collapsed with residents likely trapped under rubble.

Tymur Tkachenko, ​the head of ⁠the capital's ⁠military administration, ‌said part of a residence ​had collapsed in the eastern Darnytskyi district.

"People are trapped under the rubble," Tkachenko ​wrote on Telegram. "Emergency services are on their way ⁠to the ⁠site."

Tkachenko said buildings ‌had sustained damage in other widely separated city districts, including one where drone debris had fallen on the roof of a residential ⁠building.

Mayor Vitali Klitscho also reported damage to buildings throughout the capital, including debris that struck two buildings in a ‌northern suburb, sparking a fire in a 12-storey block of flats.

Unofficial Telegram channels posted videos of parts of apartment buildings ablaze. There were ​no immediate reports of casualties.

Ukraine's air ⁠force also said Russian ⁠missiles had targeted other ⁠regions ⁠in ​the country, including Kharkiv, Sumy ​and Chernihiv ⁠in northern Ukraine and the central region of Poltava.

800 drones fired on Ukraine Wednesday

The attack on Kyiv in the early hours of Thursday followed a day in which Russia fired at least 800 drones in a massive daytime barrage on about 20 regions in Ukraine on Wednesday.

The Wednesday offensive killed at least six people and wounded dozens, including children, in one of the longest attacks by Moscow in the four-year-old war, Ukrainian President Volodymyr Zelenskyy said.

The Wednesday attack began midmorning and lasted for hours in the capital Kyiv, the western city of Lviv near Poland, and the port of Odesa on the Black Sea, among other population centres, Zelenskyy said on the Telegram messaging app.

"Our soldiers are defending Ukraine, but Russia's obvious goal is to overload air defences," Zelenskyy said, as the bombardment stretched into the late afternoon.

It was "one of the longest, massive Russian attacks against Ukraine," Zelenskyy said on social media.

Hungary summons Russian ambassador

Wednesday's events also rattled neighbours. Hungarian Prime Minister Péter Magyar said his new government has summoned the Russian ambassador over a drone attack near Hungary's border, in a significant shift from his predecessor Viktor Orbán's friendly relations with Moscow.

"The Hungarian government strongly condemns the Russian attack on Transcarpathia," Magyar told journalists, adding that Foreign Affairs Minister Anita Orbán will speak with the ambassador Thursday morning.

The minister will ask "when Russia and Vladimir Putin plan to finally end this bloody war," Magyar said.

"Thank you for your compassion and strong position!" Zelenskyy said on social media platform X after Magyar's comments.

3 killed in Rivne region

Drone debris fell in an open area in Kyiv's Obolonskyi district with no casualties, city officials said, as air defence systems engaged Russian drones over the capital. Mayor Vitali Klitschko said emergency services responded to the scene. Explosions were heard across the city earlier Wednesday.

Three people were killed in a drone attack in the Rivne region west of Kyiv, according to Oleksandr Koval, head of the regional military administration.

Moscow's attacks are unrelenting, even as Ukraine is emboldened by its recent military accomplishments and as U.S. President Donald Trump and Russian President Vladimir Putin said — without providing evidence — that the war could be approaching an end.

"It is important to support Ukraine and not remain silent about Russia's war. Every time the war disappears from the top of the news, it encourages Russia to become even more savage," Zelenskyy said, apparently referring to the world's attention being focused on the Iran war.

A late evening statement issued Wednesday by ⁠Ukraine's military said 187 combat clashes had been recorded over 24 hours along the front line, with 55 airstrikes and 178 guided bombs deployed by Russian forces.

Putin, Trump claim war could end soon

Trump said Tuesday that he believes Moscow and Kyiv will soon reach a deal to end fighting.

"The end of the war in Ukraine I really think is getting very close," Trump said as he left the White House for a summit in Beijing. "Believe it or not, it's getting closer."

Putin said in a speech last weekend that his invasion of Ukraine is possibly "coming to an end."

Neither leader elaborated on what persuaded them about the possibility of peace in Europe's longest conflict since the Second World War. U.S.-led diplomatic efforts over the past year to end the war have fizzled after making no progress on key issues, such as whether Russia gets to keep Ukrainian land it has seized and what can be done to deter Moscow from invading again.

Kremlin spokesman Dmitry Peskov indicated Wednesday that Moscow's fundamental terms are unchanged, with Putin insisting that Ukraine pull its troops from the four regions — Donetsk, Luhansk, Kherson and Zaporizhzhia — that Russia illegally annexed in 2022 but hasn't fully captured.

"At that point, a ceasefire will be established, and the parties can calmly engage in negotiations, which, incidentally, will inevitably be very complex and involve a lot of important details," Peskov said.

Zelenskyy vowed to keep pressure on Moscow to make concessions in talks.

"We're not giving up on diplomatic efforts, and we hope that pressure on Russia, together with negotiations in different formats, will help bring peace," he said in a speech on Wednesday in Bucharest, Romania's capital.

"Sanctions are working, our long-range (drone and missile) capabilities are working, and every form of pressure is working," he said.

Meanwhile, European governments are assessing the merits of opening talks with Putin. Europe has for years tried to isolate the Russian leader and punished his country with international sanctions.

Russia launched its full-scale invasion of neighbouring Ukraine in February 2022. The two countries have been in a state of all-out war ever since.

Long-range strikes taking toll on Russia

The correlation of forces in the war has shifted in recent months. Ukraine has gone from pleading for international help with its defence to offering foreign countries its expertise on how to counter attacks, thanks to its domestically developed drone technology.

Ukraine's long-range drone and missile attacks have disrupted energy facilities and manufacturing deep inside Russia, with three regions reporting strikes on Wednesday.

The Russian Defence Ministry said that its forces intercepted and destroyed 286 Ukrainian drones over Russian regions, the illegally annexed Crimean Peninsula, the Azov Sea and the Black Sea.

On the front line, the advance of Russia's bigger and better-equipped army has been slowing every month since October, according to the Institute for the Study of War.

Russia's spring offensive has floundered, with Russian forces recording a net loss of territory last month for the first time since 2024, the Washington-based think-tank said.

"Not only are Ukrainian defensive lines holding, but Ukrainian forces have managed to contest the tactical initiative in several areas of the front line even as Russia continues to lose disproportionate amounts of manpower to achieve minimal gains," the ISW said Tuesday.
