KYIV, Ukraine (AP) — Russia launched a major air attack on Kyiv on Thursday that included a rare strike on the center of Ukraine’s capital, killing at least 21 people, wounding 48 and damaging European Union diplomatic offices, authorities said.

The bombardment of drones and missiles was the first major Russian attack on Kyiv in weeks as U.S.-led peace efforts to end the three-year war struggled to gain traction. Britain said the attack sabotaged peace efforts, while top EU diplomat Kaja Kallas summoned Russia’s EU envoy to Brussels over the strikes that damaged EU offices.

The U.N. Security Council scheduled an emergency meeting on airstrikes against Ukraine for this afternoon at the request of Ukraine and the five European council members — Britain, France, Slovenia, Denmark and Greece. Two of Ukraine’s top envoys were set to meet today with the Trump administration regarding mediation.

The Kremlin said Russia remained interested in continuing peace talks despite Thursday’s air attack, which was one of the war’s biggest since it began in 2022.

Among the dead were four children between 2 and 17, said Tymur Tkachenko, the head of Kyiv’s city administration. He said more people could still be under the rubble, and search and rescue efforts continued on Thursday evening.

Also Thursday, the Trump administration approved a $825 million arms sale to Ukraine that will include extended-range missiles and related equipment to boost its defensive capabilities as U.S. efforts to broker peace between Ukraine and Russia appear to have stalled. The State Department said Ukraine would use funding from NATO allies Denmark, the Netherlands and Norway in addition to U.S. foreign military financing to pay for the equipment.

The attack was one of the few times Russian drones and missiles have penetrated the heart of Kyiv since the start of the full-scale invasion.

Ukraine’s Air Force said Russia launched 598 strike drones and decoys and 31 missiles of different types across the country early Thursday, most of them striking targets in Kyiv.

At least 33 locations across all 10 of the city’s districts were directly hit or damaged by debris, Tkachenko said. Thousands of windows shattered as nearly 100 buildings were damaged, including a shopping mall in the city center.

Oleksandr Khilko arrived at the scene after a missile hit the residential building where his sister lives in the capital’s Darnytsia district. He heard screams from people who were trapped under the rubble and pulled out three survivors, including a boy.

“It’s inhuman, striking civilians,” Khilko said, his clothes covered in dust and the tips of his fingers black with soot. “With every cell of my body I want this war to end as soon as possible. I wait, but every time the air raid alarm sounds, I am afraid.”
