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.

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.
