(Reuters) -Russia attacked Ukraine’s capital Kyiv early on Saturday with drones and missiles, triggering fires, strewing debris in districts throughout the city and injuring at least two people, city officials said.

Mayor Vitali Klitschko said one drone struck the top floor of an apartment building in the Solomyanskyi district on the west bank of the Dnipro River, which bisects the city.

Klitschko said two people were injured in the Dniprovskyi district on the opposite bank. Emergency crews were at the site.

Timur Tkachenko, head of the capital’s military administration, said a fire had also broken out on two floors of a Dniprovskyi district apartment building, and two other fires had broken out in the western part of the city.

Drone fragments also hit the ground in several neighbourhoods, officials said.

Klitschko said anti-aircraft units were in action.

Reuters witnesses reported waves of drones flying over Kyiv and explosions jolting the city.
