Ukraine struck the Moscow region on Tuesday in its biggest drone attack so far on the Russian capital, killing at least one woman, wrecking dozens of homes and forcing around 50 flights to be diverted from airports around Moscow.

A woman died and three people were injured in the town of Ramenskoye, just outside Moscow, where drones hit two multistory residential buildings and started fires, Moscow region Gov. Andrei Vorobyov said. Five residential buildings were evacuated due to falling drone debris, Vorobyov said.
