Sao Paulo - At least 90 people died early on Sunday in a fire in a night club in southern Brazil, local television station Globo reported.

Other media said that between 50 and 70 people were killed in the Kiss nightclub in the town of Santa Maria.

The cause of the fire was unclear, though preliminary information suggested it was sparked by a pyrotechnics display during a concert. Sparks hit the soundproof foam on the ceiling and caught fire, according to Globo.

Many people were unable to reach the emergency exits in the ensuing panic.

Rescue workers were still pulling bodies from the building, while the injured were taken to local hospitals. - Sapa-dpa
