Suspected tribal rebels blew up a key pipeline in southwestern Pakistan's volatile Balochistan province on Tuesday, leaving tens of thousands of people without gas, officials said.
The pre-dawn blast suspended natural gas supplies to the provincial capital Quetta, as well as the Kalat, Mastung, Ziarat and Pishin districts, a gas company official said on condition of anonymity.
Repair work had started on the ruptured section of pipeline at Dasht, near Quetta, and supplies will hopefully be restored later on Tuesday, the official added.
The attack was the third of its kind since Monday when two other pipelines were blown up elsewhere in Balochistan.
Rebels also attacked a passenger train with rockets on Thursday but caused no casualties.
Tensions have soared in gas-rich Balochistan since the army killed rebel tribal chieftain Nawab Akbar Bugti in his cave hideout in a major operation on August 26.
Insurgents linked to Bugti have waged a two-year campaign to win more political rights and a greater share of profits from the region's natural resources.
