A fire erupted at a film studio in the southern city of Mysore during the shooting of a television serial, killing at least 36 people and injuring 55 others, the Press Trust of India said Thursday.

The news agency said the blaze Wednesday night at the studio in Mysore, located in Karnataka state, 1,130 miles south of New Delhi, was sparked by exploding firecrackers.The fire raged through a floor on which filming was under way for a segment of a 52-part television series titled "The Sword of Tipu Sultan," a portrait of a Mogul-era ruler who resisted India's British colonizers.

The flames trapped members of the show's 60-member production unit on the floor, and other studio personnel were prevented from fleeing the building because the doors had been locked to prevent members of the public from entering, the Press Trust said.
