Russia strikes Kyiv after first stage of major prisoner swap

Russia has launched 250 drones and 14 ballistic missiles against Kyiv, Ukraine's air force said, in one of the biggest combined aerial attacks on the Ukrainian capital of the three-year conflict.

The strikes caused damage to several apartment buildings and injured 15 people.

Ukrainian President Volodymyr Zelenskyy said it had been a "tough night" for Ukraine, and called for new international sanctions to pressure Moscow into agreeing to a ceasefire, in a social media post.

Ukrainian Foreign Minister Andriy Sybiga said on X the barrage was "clear evidence that increased sanctions pressure on Moscow is necessary to accelerate the peace process."

The Russian military said Ukraine had targeted it with 788 drones and missiles since Tuesday, 20 May.

The attack on Kyiv came hours after Russia and Ukraine took part in a prisoner swap agreed after talks between the two countries' officials in Türkiye.

Both sides received 390 people in the first stage and are expected to exchange 1,000 each in total.

Russia has signalled it will send Ukraine its terms for a peace settlement after the swap, which is set to continue over the weekend, without saying what those terms would be.

U.S. President Trump said, after a call with Vladimir Putin, that Russia and Ukraine would 'immediately start' ceasefire talks. But Putin only mentioned working on a 'memorandum for a possible future peace deal' and did not respond to calls for a 30-day ceasefire.
