PESHAWAR - At least twelve militants were killed and 14 others including several foreigners were injured on Sunday when a drone of US-led NATO forces fired two missiles at a suspected hideout of militant forces in village Haibatkhel of Sararogha tehsil in South Waziristan Agency on Sunday, security official said. The local tribesmen while confirming the attacks, said that immediately after the missile strikes the house collapsed and caught fire. They also informed that around nine dead bodies have been recovered from the debris so far. According to them, several foreign al-Qaeda operatives are among the dead and the injured. However, their exact identity has not been ascertained yet. The targeted house is said to be a hideout of al-Qaeda's foreign and local operatives. Agencies add: "Two missiles fired by a suspected US drone hit a compound in Sararogha, in South Waziristan region," a security official told. The region, bordering Afghanistan, is a known haven for Taliban and Al-Qaeda extremists. "It was a Taliban sanctuary, which was destroyed in the attack," a security official said. "Some foreigners were possibly among those killed in the attack," he said. This was the fourth missile strike by unmanned US aircraft since President Barack Obama came to power. A suspected US missile strike on February 16 destroyed an Afghan Taliban camp and killed 26 in Pakistan's northwest tribal area of Kurram. Pakistan is a key ally in the US led "war against terrorism". But the strikes have fuelled anti-American sentiments in Pakistan and particularly in the tribal belt, where Washington says Al-Qaeda and Taliban sanctuaries exist. The lawless tribal areas have been wracked by violence since hundreds of Taliban and Al-Qaeda rebels sought refuge in the region after the US-led invasion of Afghanistan toppled the Taliban regime in late 2001.
