Bugti tribesmen have joined forces with the Marri tribe and are digging trenches along the road leading to the FC fort, where 300 troops, government officials and their families have been besieged, a Frontier Constabulary spokesman claimed on Monday. The spokesman said that more than 50 armed tribesmen had taken positions in the trenches and the FC, through the government, had conveyed a message to them that such confrontation would lead to more damage, Online reported. The FC also warned them against taking law into their hands, he said. The spokesman said that FC was using helicopters to provide supplies to their people and was avoiding the road. The tribesmen are apparently preparing for more battles, he added. Aziz Sanghur from Karachi adds: Aga Shahid Bugti, the secretary general of the Jamhoori Watan Party, said on Monday that the government's claim that tribesmen had surrounded its 300 personnel was false. Talking to Daily Times, the JWP official said that appeals by the Balochistan governor and other government officials to the tribesmen to lift the siege were aimed at misguiding the people. He said the federal government had decided to launch a massive army operation in Dera Bugti and around 130 trucks of regular troops entered Sui on Monday morning.
