KYIV (AP) — A rescue worker says at least six civilians were injured by a rocket that hit a high-rise apartment building on the outskirts of the Ukrainian capital.

Security camera video released by the mayor of Kyiv, Vitali Klitschko, shows the moment of the strike. The aftermath was a gaping hole on one side of the apartment building.

Petro Prokopov, a firefighter who was taking part in rescue efforts, said the building on the southwestern edge of Kyiv near Zhuliany airport was hit between 16 and 21 floors on Saturday. He said at least six people were injured and apartments on two floors were gutted by fire. Emergency responders have evacuated 80 people.

Separately, Ukraine’s Infrastructure Ministry said a Russian missile was shot down before dawn Saturday as it headed for the dam of the sprawling water reservoir that serves Kyiv.

“If the dam is destroyed, the flooding will cause catastrophic casualties and losses – including flooding of residential areas of Kyiv and its suburbs,” the ministry said.
