Ukrainian drones attacked Moscow for the second consecutive night, temporarily halting flights at four airports in the Russian capital and nine further afield – as it prepares to host a major military parade expected to be attended by world leaders including China’s Xi Jinping.

Twice in the past two days, Ukrainian drones have threatened Moscow, but it is unlikely they will disrupt the Kremlin’s showcase Victory Day celebration.

Russia says Ukraine launched a drone attack on Moscow - days before the start of a ceasefire, ordered by Russian President Vladimir Putin to coincide with a World War Two parade. Moscow's four major airports shut for a few hours on Tuesday amid the barrage, authorities said. There were no casualties and Ukraine has not commented.
