A massive explosion at a government-owned steel plant in the southern Indian state of Andhra Pradesh has killed at least 11 people, police say.
The blast triggered a fire in the plant in the coastal city of Visakhapatnam. At least 16 other workers suffered serious burn injuries.
The blast took place in an oxygen tank in the plant when workers were installing new equipment, reports said.
The death toll is expected to rise as some of the injured are critical.
