LONDON and KHARKIV, Ukraine — Russia launched overnight a deadly aerial strike on the Ukrainian capital, killing at least one person, injuring 19 others and damaging residential buildings, President Volodymyr Zelenskyy of Ukraine said early on Sunday. 

“Emergency response efforts are currently underway in Vyshhorod, Kyiv region, following the Russian attack,” Zelenskyy said on social media. “Russia struck the city with drones, damaging numerous residential buildings.”

The attack came as Zelenskyy and his top advisers traveled to the United States for high-stakes talks with the Trump administration over its proposed plan for peace between Russian and Ukraine. 

Zelenskyy on Sunday morning said Russia launched a total in the last week of about 1,400 drones and 66 missiles, as well as over a thousand aerial bombs, against Ukraine, underlining the scale of Russia’s increased air campaign as peace talks go on.

“This is exactly why we must strengthen Ukraine’s resilience every single day,” Zelenskyy said. “Missiles and air-defense systems are essential, and just as crucial is active work with our partners for peace. We need real, reliable solutions that will help end this war. I thank everyone who is helping.”
