A gas cylinder blast in a house at Dholahat in West Bengal's Pathar Pratima has claimed eight lives, including four children. The explosion, which occurred on Monday night, triggered a massive fire, intensified by the presence of stacked firecrackers inside the house. The incident has sparked a political controversy, with the BJP demanding a National Investigation Agency (NIA) probe and the TMC maintaining that the police are already investigating and that the state government has a "zero-tolerance " policy towards such incidents. The blast has also raised concerns about the safety of illegal firecracker manufacturing units, which have been linked to several recent accidents in the state.
Another explosion "linked to illegal firecrackers" took place in West Bengal on Monday, the third such blast within a span of just seven days.
The police seized a huge quantity of explosives and banned firecrackers during raids in different locations in rural West Bengal and arrested at least 100 people for their alleged involvement in running illegal manufacturing factories, a senior state police official said on Tuesday.
The impact of the explosion "was so massive" that the factory, which was being run from a residential building, collapsed, the police said.

Rescue officials confirmed casualties in the incident, claiming to have already recovered 5 bodies from the heap of debris where the cracker manufacturing unit once stood.
