Twenty-one people were killed when a passenger train hit an overloaded rickshaw at a level crossing in eastern India, a railway official said.

Vinod Kumar said the driver of the motorised rickshaw and all its passengers died in the accident in Bihar state.

The crossing gate was open and the rickshaw was crossing the track when the train hit it, dragging it for about 500 yards, Mr Kumar said.

Seven children and six women were among the dead. They were returning from offering prayers at a temple near Motihari, a town in Bihar.

Railway accidents are common in India, which has one of the world's largest networks. More than 23 million passengers daily use India's 11,000 passenger trains.
