A series of Russian strikes hit a residential neighbourhood of Ukraine's capital on Tuesday, igniting a huge fire and frantic rescue effort in a 15-story Kyiv apartment building.?

At least one person was killed and others remain trapped inside.

The Ukrainian military said in a statement that the strikes were artillery strikes. They hit the Svyatoshynskyi district of western Kyiv, adjacent to the suburb of Irpin that has seen some of the worst battles of the war.

Flames shot out of the apartment building as firefighters rescued people from ladders. Smoke choked the air.

A firefighter at the scene confirmed one person died and that several have been rescued alive but others are still inside as rescuers try to reach them.

Russian forces also stepped up strikes overnight on the northwest suburbs of Irpin, Hostomel and Bucha, the head of the Kyiv region Oleksiy Kuleba said on Ukrainian television.

Russian forces also renewed efforts Tuesday to capture the important port city of Mariupol in the south, and unleashed new artillery strikes on downtown Kharkiv in the east, the general staff of Ukraine's armed forces said on Facebook.
