A massive blaze broke out in a firecracker factory on Saturday in central India, killing at least 15 people, police said.
The workers were making firecrackers when the fire started, police officer Kishore Gurjar said. It was doused and all the workers were accounted for.
The four injured workers were battling for their lives in a hospital.
Local media reports said the death toll was expected to rise.
Police have said the cause of the fire was not immediately known and was being investigated.
There are fatal accidents nearly every year in India as people work in makeshift factories, often employing children in the absence of proper safety standards.
India has a huge demand for firecrackers, which are used in religious festivals and weddings.
Factories start producing crackers months before the nation\’s biggest Hindu festival, Diwali, or Festival of Lights, when people set off fireworks in celebration.
