Ukraine's President Volodymyr Zelenskiy said on Sunday that Russia launched more than 200 drones in an overnight attack, the largest of the war, as he condemned Russia's "aerial terror" and called for unity among Ukraine's allies.

President Trump stepped up pressure on Kyiv to agree to a deal at talks. Russia later launched more than 250 drones at Ukraine, Kyiv said.

British Prime Minister Keir Starmer said on Sunday that there can be no talks about the future of Ukraine without the participation of Ukraine, setting his stall out before a meeting with U.S. President Donald Trump this week.

President Donald Trump said he's had "good talks" with Russia's Vladimir Putin but not with Ukraine, and that he's "sick" of how Volodymyr Zelenskyy has handled the war.

President Donald Trump reversed course on Friday and said Russia did in fact invade Ukraine, and that Kyiv would soon sign a minerals agreement with the United States as part of efforts to end the Ukraine war.
