The volley came just days before a planned parade in the capital to mark the 80th anniversary of the end of World War II in Europe.

All four international airports around Moscow temporarily suspended flights Tuesday as Russian forces intercepted more than 100 Ukrainian drones fired at almost a dozen Russian regions, the Defense Ministry in Moscow said.

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.
