Taliban rebels decapitated four pro-government tribal elders in Bajaur where the army is fighting Al-Qaeda and extremist militants, officials said Saturday. It was the second killing this week in Bajaur of tribal elders, who have established an armed force to support the government's military campaign against Al-Qaeda and Taliban fighters in the area. "This morning locals reported bodies of four tribal elders were lying on roadside," local administration official Mohammad Jamil told a foreign news agency, adding that the bodies showed extensive signs of torture. A security official who declined to be named said the beheadings had been done by Al-Qaeda and Taliban militants to scare the local population away from supporting the army operations.
