The fire engulfed the club at around 1:00 a.m. local time. At least 134 people are injured, of whom half are in a serious condition, the emergencies ministry said.

Regional security minister Igor Orlov told media that the club's plastic ceiling caught fire during the pyrotechnics display, held during a celebration of the venue's seventh anniversary.

The health ministry has said that the injured are being flown to Moscow, to be treated in the city's best hospitals. Their plane is scheduled to land in the capital at 11:30 a.m. Moscow time (08:30 GMT).

Investigators have so far identified 10 of those killed in the fire.

The venue, which covers an area of 500 square meters, was almost completely destroyed by the blaze.
