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 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 as Russia said its forces intercepted more than 100 Ukrainian drones.
