Ukrainian drones attacked Moscow for the second consecutive night temporarily halting flights at four airports, Russian officials said, as the city prepares to host a major military parade expected to be attended by world leaders including China’s Xi Jinping.

Russia on Friday paraded combat drones that its forces use in the war in Ukraine on Moscow's Red Square in what state TV said was a first.

Russian authorities say drone attacks by Ukraine have caused flight disruption at Moscow’s main airports for a third straight day.
