An explosion occurred at a firecracker factory in Champahati, West Bengal's South 24 Parganas district, on Saturday, critically injuring four people. The blast caused a fire, which fire tenders worked to extinguish. The injured were taken to local hospitals and then transferred to Kolkata, with one reportedly suffering severe burns. The cause of the explosion is under investigation, with preliminary suggestions pointing to mishandling of materials. Locals reported a deafening blast, and the factory owner is reportedly absconding. This incident follows a similar fatal explosion at a Champahati factory in December 2024.
