At least one person has been killed after 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.

A Ukrainian drone attack on a beach in the Russian city of Kursk killed three people, including a Russian serviceman engaged in rescue operations, and injured seven, acting regional Governor Alexander Khinshtein said early on Wednesday.

We’ve been verifying video being posted online from Ukraine following an overnight Russian attack involving around 400 drones and 18 missiles, according to the country’s President Volodymyr Zelensky. Ukraine’s worst hit area was Kyiv, he said, where two people were killed. He reported five other regions were hit.

Russian’s transport minister was found dead hours after being dismissed by President Vladimir Putin, in what officials said was an apparent suicide.
