An overturned fuel tanker exploded on Tuesday night in northern Nigeria, killing at least 153 people who had rushed to the scene of the accident to collect leaking petrol, officials say. The fire engulfed the vehicle, which had been cordoned off by officers after it crashed in Jigawa state, the police told the BBC. About 100 other people injured in the explosion have been taken to hospitals in the region, many of them in critical condition.
