Four workers killed in explosion at Tamil Nadu fireworks unit

Four workers were killed and another person was injured in Tamil Nadu's Virudhunaga on Saturday following an explosion at a firecracker manufacturing unit, police said. The workers were killed on the spot and the cause for the explosion and blaze is suspected to be mishandling the chemical ingredients, the raw materials, that go into the making of firecrackers, a senior district police official said.


Another person who was in the vicinity was injured and buildings --rooms earmarked for specific tasks involved in manufacturing processes-- have suffered damage, he added.
