All four international airports around Moscow temporarily suspended flights as Russia said its forces intercepted more than 100 Ukrainian drones.

Ukrainian drones attacked Moscow for the second consecutive night temporarily 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.

The attacks on Moscow come days before a Putin-announced three-day ceasefire, and a major parade in the Russian capital.
