At least two people were burned to death and two others critically injured in an explosion at a gunpowder manufacturing unit in Rajasthan's Nagaur district on Thursday morning.

The blast occurred at around 9:40 a.m. in the Badli area, triggering fears that more workers could still be trapped inside the premises. The explosion was so powerful that its sound was heard nearly half a kilometre away, triggering panic among local residents.
