At least eight persons were killed and seven injured in U.S. drone missile attacks at Sararogha area in South Waziristan Agency (SWA). Sources said that the U.S. drones fired four missiles on one house and madrassa at Sararogha area of South Waziristan, which left at least eight killed and seven wounded. The local people helping themselves recovered eight bodies from under the debris, while seven persons were wounded, sources said. A suspected US drone fired missiles at a compound used by militants in a northwestern Pakistan tribal area bordering Afghanistan Saturday, causing casualties, officials said. The missiles hit a compound at Tabbi Langar Khel village in restive South Waziristan tribal district bordering Afghanistan, two security officials said. "I can confirm a missile strike at a compound at Tabbi Langar Khel," one of the security officials said. "According to initial reports there could be casualties," the official said, adding that insurgents were active in the area where missile strike took place. The latest drone strike comes as Pakistani President Asif Ali Zardari is visiting the United States. Around 370 people, including suspected militants, have died in around 39 such attacks since August 2008. Pakistan has paid a heavy price for its alliance with the US in its global fight against extremism with militant attacks killing more than 1,700 people since July 2007. The US military does not, as a rule, confirm drone attacks, but its armed forces and Central Intelligence Agency (CIA) operating in neighbouring Afghanistan are the only forces that deploy drones in the region.
