Suspected militants ambushed a military convoy in Balochistan on Wednesday, killing two soldiers and wounding four, officials said. Insurgents positioned on mountains overlooking a road attacked the convoy with rockets and machine guns at Pinjra Pull, 70 kilometers southeast of Quetta, a security official said. “The troops, who were on their way to nearby Sibi for a routine deployment, retaliated and the exchange of gunfire continued for about half an hour,” the official speaking on condition of anonymity, said. At least one soldier died and five others were wounded, the official said, adding that the casualties occurred after a military vehicle was hit. The attackers fled into the mountains after the ambush, he said. No one has claimed responsibility for the attack.In a separate incident, four soldiers were injured when a landmine planted by suspected rebels exploded beneath a military vehicle in Sibi on Tuesday, officials said. Attackers also blew up small pipelines feeding natural gas from two wells to a filtration plant, the second such attack in two days in Balochistan’s Dera Bugti district, they said. Saboteurs blew up the pipeline from Well No 23 of the Pirkoh Gas Field and stole valves from Wells 13 and 16 on Wednesday
