AFP adds: Officials said Thursday that troops were vacating a key fort in South Waziristan, identified by the United States as a haven for militants. The British-era fort in South Waziristan is being turned into a hospital for local tribesmen and some 300 troops have begun leaving, said Major General Mohammad Alam Khattak, head of the paramilitary Frontier Corps. The fort in the town of Ladha is in an area dominated by Baitullah Mehsud, top Taliban commander and the man accused by the last government of masterminding the slaying of former premier Benazir Bhutto. Khattak denied that pressure from the militants was behind the decision to vacate the fort, where more than a dozen troops were killed in a series of militant offensives in January. "The decision has been taken to provide health facilities to local tribesmen," Khattak told reporters in Peshawar. "The fort had no strategic value for us. It was located in a depression surrounded by populated area," he said, adding that the troops would be moving to Wana, the main town in South Waziristan. He said the fort, built in 1932, had faced at least 18 major attacks in recent years. "There have been heroic battles around the fort and our troops defended the fort with bravery and courage," he said.
