Russia struck Ukraine's Kyiv region with ballistic missiles and drones Monday, killing at least 11 people and wounding dozens, authorities said, a day before a NATO summit begins in Türkiye's capital Ankara.
The assault was the second on Kyiv and surrounding areas in less than a week and came as Russia and Ukraine stepped up long-range attacks.
U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy are expected to discuss the war on the sidelines of the NATO summit, which begins Tuesday.
Trump also plans to speak with Russian President Vladimir Putin afterward as Washington seeks to revive stalled peace efforts to end the four-year war.
An Agence France-Presse (AFP) journalist in Kyiv heard more than 10 explosions during a ballistic missile alert early Monday. Around 30 minutes later, AFP journalists saw several flashes in the sky as another series of blasts rang out.
Authorities said 10 people were killed in Kyiv and one in the Bucha district northwest of the capital. At least 46 people were wounded in Kyiv and 15 others in surrounding areas.
Tymur Tkachenko, head of the Kyiv region's military administration, said the attack caused four fires, all in residential buildings.
"Places where people were simply sleeping tonight," he wrote on Telegram.
Russia's Defense Ministry said it had carried out a "massive strike" using missiles and drones against what it described as "military-industrial enterprises" and fuel and energy facilities in several Ukrainian regions.
Ukraine has increasingly targeted energy facilities inside Russia in recent weeks in an effort to weaken the Kremlin's war effort. It has also struck Moscow-controlled territory in Ukraine that predates the current invasion.
In Russian-annexed Crimea, governor Mikhail Razvozhayev said a Ukrainian strike near Sevastopol temporarily cut electricity supplies.
"Our energy workers have managed to reconnect power via backup schemes to almost all facilities, and electricity has been restored to most residential buildings in Sevastopol," Razvozhayev wrote on Telegram hours after the attack.
Moscow Mayor Sergei Sobyanin said on state-backed Max that several waves of drones headed for the Russian capital were shot down by Russian air defenses.
Russia's Defense Ministry said its forces shot down 519 Ukrainian drones across more than 20 regions overnight, including around Moscow and Russian-annexed Crimea.
The White House said Trump would meet Zelenskyy on Wednesday during the NATO summit.
"The president's obviously getting together with him to talk about how we can end the war. That's been a priority of his for a long time," a senior U.S. official said, speaking on condition of anonymity.
The official said Trump would then "follow up" with Putin.
The meetings come as diplomatic efforts to end the war remain largely stalled.
Zelenskyy said Sunday that Ukrainian troops were continuing to fight for the strategic eastern town of Kostyantynivka, a gateway to key positions in the Donetsk region.
Russia claimed Friday to have captured the town, but Kyiv dismissed the announcement as "a lie."
"Fighting is also continuing for Kostyantynivka, which Putin has already claimed as his own, but it is obvious that he will never dare to appear there," Zelenskyy said in his nightly address.
Putin and Zelenskyy held separate phone calls with Trump on Saturday to mark the 250th anniversary of U.S. independence.
