Russia launched its largest drone attack on Ukraine since the beginning of its invasion, Ukrainian officials said Wednesday, just hours after US President Donald Trump pledged more military support for Kyiv and accused his Russian counterpart Vladimir Putin of throwing “bullsh*t” over peace talks.

Trump said after a call last week with Putin that he was unhappy with Russia’s president and “I don’t think he’s looking to stop” the war. Then, speaking at the start of a dinner he hosted for Israeli Prime Minister Benjamin Netanyahu at the White House on Monday night, Trump said, “I’m not happy with President Putin at all.”
