Ukrainian drones attacked Moscow for the second consecutive night 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's three-day ceasefire in Ukraine is due to begin on Thursday, but Zelensky has dismissed the proposed truce as a "theatrical play".

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.
