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.

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.

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.
