Russian forces bomb Mariupol theatre where hundreds of civilians were sheltering

The deputy mayor the besieged port city of Mariupol has told the BBC that Russian forces have bombed a theatre where hundreds of civilians were sheltering.

Serhiy Orlov said between 1,000 and 1,200 people were in the building. The number of casualties was still unknown, he said.

Mariupol has been encircled by Russian forces, and an estimated 300,000 are trapped with no running water, electricity or gas. Food and medical supplies are running low, and Russia has not allowed the delivery of humanitarian aid.

The city has been under constant Russian shelling since the start of the war, and entire neighbourhoods have been turned into wasteland. Last week, an attack on a hospital left five dead.
