Ukrainian President Volodymyr Zelenskiy said on Friday that interceptor drones had proved effective in downing many Russian drones deployed in an overnight Russian attack on Kyiv and issued a new call for their rapid development and production.

Russia launched 550 drones and missiles across Ukraine overnight in the largest aerial assault since the war began. The capital Kyiv was the primary target.

Ukraine destroyed three Russian attack helicopters in its latest blow to Moscow’s air power, Kyiv has claimed.
