The Kremlin said on Wednesday that attempted overnight Ukrainian drone attacks on Moscow ahead of the commemorations of the 80th anniversary of the victory of the Soviet Union over Nazi Germany showed Kyiv's tendency to commit "acts of terrorism.

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.

The attacks came a day before a Russian-proposed cease-fire was to take effect and as Moscow prepared to welcome foreign dignitaries for a parade.
