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.

The latest assault included more drones in a single night than Russia used in the entire month of July last year.

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.

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

The truth is, he believed me 10%,' Trump said of the threat he made to Putin that he would bomb Moscow if Russia invaded Ukraine.
