MINGORA, Sept 21: The whole Swat district plunged into darkness as the Aman Kot power grid station was blown up in the early hours of Sunday.

Sources said that unidentified miscreants entered the grid station in the vicinity of Mingora, the district headquarters, at 5am and held up the five to six staff members at gun point. They tied their hands with ropes and planted improvised explosive devices around the grid station. A watchman was injured in the incident.

The injured watchman told the media that a group of armed masked men came to the grid station and tied all staff members with ropes. They blew up the grid station with remote control bombs. The district, except Barikot to Mingora, plunged into darkness as the main power supply line to upper Swat disconnected due to the explosion. Electricity supply to Kanju, Kabal, Deolai, Khwazakhela and Kalam had already been disrupted for the last 20 days.
