July 7 (UPI) -- Ukraine attacked the Moscow region with more than 430 drones overnight, its largest assault on the capital and surrounding areas in two years, Russian authorities said.

Moscow Mayor Sergey Sobyanin told the state-run TASS news agency that there were 430 incoming unmanned aerial vehicles between late Monday night and 6 a.m. local time Tuesday.

Sobyanin said that air defenses downed most of the drones "at distant approaches," but 36 got close to Moscow before being destroyed.

The assault came after the mayor reported more than 200 drones heading toward the Moscow region on Saturday. Most of those were also downed at some distance from the capital by air defenses.
