Tribal insurgents early on Sunday blew up a gas pipeline in Balochistan, disrupting supplies to the area, officials said. The pre-dawn blast damaged the main pipeline in the Loti gas field, 450 kilometres southeast of Quetta, a gas company official said. Requesting anonymity, he said that the attack affected gas supplies to local consumers. He blamed rebels, who are fighting for greater autonomy and a share of profits from the region's natural resources. Sunday's attack was the fourth on gas pipelines in the province this month.
