Thirty seven people, mostly women and children, were killed in Bihar this morning when an express train ploughed into pilgrims at a remote and poorly connected area in the state's Khagaria district, around 160 km from Patna. The incident at 8:40 am triggered mayhem at the Dhamara Ghat Station, as a violent mob reportedly assaulted the train driver, set trains on fire, vandalized the station and held railway staff hostage.
