At least five people were killed and seven injured in a huge explosion at a chemical factory at Boisar in Maharashtra's Palghar district, over 100 km away from Mumbai, a police official said on Saturday.
The under-construction plant of Ank Pharma, where the explosion took place, is located in a Maharashtra Industrial Development Corporation (MIDC) area at Kolwade village, the official said.
