US President Donald Trump claimed that progress toward ending the Ukraine war, which has lasted over four years, is occurring faster than the public perceives, after weekend phone calls with Russian leader Vladimir Putin and Ukraine's Volodymyr Zelenskiy. He plans to discuss the matter at a NATO summit in Turkey. Trump did not provide a basis for his assertion, even as a Russian missile and drone strike on Kyiv and the surrounding region killed at least 28 people. Trump is set to meet Zelenskiy on the summit's sidelines, and a US official said the talks aim to renew diplomatic efforts. Trump also described a lengthy call with Putin, during which he offered to assist peace efforts.
