The volley comes just days before a planned parade in the capital to mark the 80th anniversary of the end of World War II in Europe.

A Russian overnight drone attack on Kyiv injured at least 11 people, including two children, and set several residential buildings throughout the city on fire, the military and officials of the Ukrainian capital said on Sunday.

A Ukrainian drone attack prompted Moscow to close its airports temporarily. The attack precedes Russia's Victory Day parade, with international leaders urged to boycott the event, citing concerns over Russia's ongoing aggression in Ukraine.
