KYIV, Ukraine -- Russia targeted Ukraine overnight with 322 drones, 292 of which were "neutralized" by being either shot down or supressed by other means, according to the Ukrainian air force. Eleven people, including two children, were injured in the Kharkiv area, in a drone strike overnight there, according to local emergency services.

Ukraine said Saturday it struck a Russian airbase in the Voronezh region. Russia has not confirmed the attack.

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.
