Two persons were killed and 17 others injured in a massive fire triggered by a blast in a boiler of a chemical factory in Maharashtra's Nashik district on Sunday, police officials said.

The blast in the Jindal Poly Films factory, located in Mundhegaon along the Mumbai-Agra highway in Igatpuri taluka, was so strong that it was heard in nearby villages. The fire and smoke could be seen from a distance. The incident occurred around 11.30 am, they said.
