Kyiv, Ukraine officials said a Russian airstrike hit a residential area in Kramatorsk, with the impact damaging an apartment block and prompting emergency response on Sunday. Ukrainian authorities said the attack killed one person and wounded two.

The strike occurred in the city of Kramatorsk, in Ukraine’s Donetsk region, where the Ukrainian State Emergency Service said the airstrike started a fire in a nine-story apartment building. Ukrainian officials framed the attack as part of ongoing Russian shelling and airstrikes across eastern Ukraine.

Separately, Ukrainian energy-related officials said Russia struck infrastructure in the Poltava region overnight into Sunday. Serhii Koretskyi, chief executive of the state-owned gas company Naftogaz, said the strikes targeted energy infrastructure.

Zelenskyy said the airstrike news arrived amid renewed diplomatic pressure. Zelenskyy told reporters Friday that the U.S. had given Ukraine and Russia a June deadline to reach a peace deal to end the war.

Zelenskyy said in comments reported by the Associated Press that the U.S. proposed ending the war by the beginning of this summer and would likely apply pressure based on that schedule. He also said the U.S. wanted a “clear schedule of all events” tied to the June timeline.

Zelenskyy said the U.S. proposed holding the next round of trilateral talks next week in their country for the first time, likely in Miami, and that Ukraine confirmed its participation. He pointed to earlier U.S.-brokered trilateral talks in Abu Dhabi that produced no breakthrough, saying the sides continued to hold mutually exclusive demands.

The previous set of talks underscored that Russia is pressing Ukraine to withdraw from the Donbas, where fighting remains intense, a condition Kyiv has said it will never accept.
