ISLAMABAD: US missiles killed three alleged Arab militants Tuesday in a tribal region along the Afghan border, Pakistani intelligence officials said. The officials said two drone-fired missiles hit a vehicle in the Baghar area of South Waziristan, an area that has been used by militants to cross into Afghanistan, where many are involved in fighting US, NATO and Afghan forces. The two officials spoke on condition of anonymity because they were not authorized to speak to the media. The official said local informants and intercepted satellite phone conversations indicated that the militants killed were Arab. Tuesday's strike was the second drone attack since US Navy SEALS conducted a raid on May 2 that killed Al-Qaeda chief Osama Bin Laden in Abbottabad, Pakistan, a garrison city that also lies in the country's northwest.
