All trains running on the Pathankot-Amritsar track were halted for three hours today after calls about bombs being planted on the track were received here. A phone call from the Divisional Manager, Ferozepur, to the control rooms of the Gurdaspur and Pathankot police in the forenoon today claiming that a bomb was planted by militants somewhere on the Pathankot-Amritsar track was enough to spur police officers of three police districts into action.
