Hundreds of Russian drones flying from all directions attacked Kyiv overnight into Thursday in an apparent new Russian tactic, marking a second consecutive night of ferocious attacks on Ukraine.

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.

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