Four killed after water pipe bursts in Russian mall

Media reports estimated the number of injured to be between 50 and 70, and said many had to be hospitalised.

Those killed were all employees of a food market in the shopping centre, according to the Russian state news agency Tass.

Video footage showed flooding throughout the building and steam flowing out of a doorway.

The mall, known as Vremena Goda (The Seasons), opened in 2007 and houses more than 150 stores.

"We are providing medical assistance to all the victims," Sobyanin said.

So far the causes for the pipe bursting are unknown.
