Three persons were killed and 10 others sustained injuries after an explosion occurred at an illegal firecrackers manufacturing unit in Madhya Pradesh's Damoh district on Tuesday, an official said.
Fire safety experts have said that untrained workers are largely responsible for the spate of disasters. Using banned chemicals is another prominent reason for the blasts.
Prime Minister Narendra Modi condoled the loss of lives in the accident and announced an ex-gratia of Rs 2 lakh each to the kin of the deceased from the Prime Minister's National Relief Fund
