QUETTA, Aug 15: Two gas pipelines – one in the Pir Koh gas field and the other in Lakpass area – were blown up on Friday, suspending supply to the Sui plant and Mastung town.

Also in Mastung, a house was damaged after unidentified men hurled a hand-grenade.

Official sources said that a bomb planted under the main pipeline supplying gas to the Sui purification plant from the Pir Koh gas field exploded late on Friday night.

“A five-foot-long portion of the 18-inch pipeline was blown up in the blast,” the sources said, adding that supply to the Sui plant was affected.
