The toll in the Balaghat firecracker factory explosion rose to 25, and most of the deceased are believed to be workers employed in the factory.
An explosion had occurred on Wednesday at a firecracker factory at Kater, almost 5 km from district headquarters town of Balaghat, in Madhya Pradesh.
Thirteen people were killed in April in a massive fire at a government-run fuel and grain depot in Madhya Pradesh.
At least eight others were critically injured and hospitalized in the explosion Wednesday evening in the village of Khairi in Balaghat district.
"We started rescue works as soon as the information was received".
"It is a matter of investigation to find out the actual cause of fire", a senior police official said.
Balaghat collector Bharat Yadav said the reason behind the explosion could not be immediately ascertained and an inquiry has been ordered into the incident.
Shivraj Singh Chauhan, chief minister of Madhya Pradesh, announced a compensation of around $3,000 for the families of the deceased. According to Yadav, the victims were the workers of the factory and the incident took place when the work was on.
The powerful explosion threw away several bodies out of factory, the account of the injured woman worker said.
