A fire at one of the Indian army’s largest ammunition depots triggered a series of explosions but caused no injuries, officials say.
Military spokesman Mahesh Upasani said the fire was at the Panagarh army base 120km (75 miles) west of Calcutta. He said it was now under control.
However he said 150 tonnes of explosives and ammunition kept at the base was destroyed.
Earlier this week a fire broke out in Calcutta, killing at least 24 people.
Officials say that the cause of Friday’s fire – which caused panic in nearby villages – is being investigated.
The full extent of the damage was not immediately known.
