DERA GHAZI KHAN/QUETTA, Feb 5: Unidentified saboteurs blew up a gas pipeline in Punjab and a railway track in Balochistan on Saturday.

Gas supply to several cities in southern Punjab and a power generation plant was suspended following an explosion in the main pipeline originating from Dhodak gas and oil fields in Taunsa, 90km from D. G. Khan, on Saturday night.

The blast occurred at 8.30pm at Mangrotha East. It suspended gas supply to Dera Ghazi Khan, Kot Addu, Taunsa Sharif and KAPCO power plant.

The Dhodak plant manager confirmed the blast but said it was not clear whether it was a terrorist activity or an accident. He said that gas supply from the plant had been suspended.

It is the third blast in DG Khan during the last week. In the earlier two blasts, railway track was damaged in Shadan Lund and Kot Chhutta.

DG Khan and Rajanpur districts, it may added, are situated along the troubled Kohlu and Dera Bugti areas of Balochistan.

The Baloch nationalists want the two Suleman range districts of Punjab annexed with their province.
