The owner and manager of a nightclub in Russia's Urals where a fire killed at least 102 people during the night have been arrested, investigators said.

The fire engulfed the Lame Horse club in the city of Perm at around 1:00 a.m. local time during an indoor fireworks display. At least 134 people are injured, of whom half are in a serious condition, the emergencies ministry said.

Russian Investigation Committee spokesman Vladimir Markin told RIA Novosti that the club's owner, Anatoly Zak, and manager Svetlana Yefremova, have been arrested on charges of causing loss of live by breaching fire safety regulations. They face jail terms of seven years.

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.
