The more drones in a single attack, Kuzan says, the more Ukraine hard-pressed air defence units struggle to shoot them down. This forces Kyiv to fall back on its precious supply of jets and air-to-air missiles to shoot them down.

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.

President Trump is openly voicing his frustration with Vladimir Putin as Russia intensifies attacks while the U.S. tries to broker peace.

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.
