At least 64 people died in a fire in a shopping mall in the Siberian city of Kemerovo on Sunday.

News agencies reported more than 100 people had been evacuated from the mall, which contains cinemas, restaurants and shops.

There was no immediate indication of the cause of the fire. Television pictures showed people jumping from the windows of the mall, which was engulfed in black smoke. Kemerovo is a coal-producing region some 3,600 km (2,200 miles) east of Moscow.

Russia’s emergency ministry said that six people are still trapped in the rubble of the smouldering Winter Cherry shopping centre in Kemerovo.

The fire broke out at the shopping center on a busy Sunday afternoon and quickly engulfed the top floor of the building, spreading through a children’s ice-skating ring, play center and a two-screen cinema.

Authorities on Monday said four arrests had been made in connection with the fire.
