Pakistani government air raids have killed up to 45 militants, their family members and other civilians with no ties to the fighters, officials said on Wednesday. Three strikes on Tuesday night targeted in the Tirah Valley in the northwestern Khyber region on the Afghan border. "We have reports that 40 to 45 terrorists were killed," a security official told Reuters. On the other hand a private TV reported that several women and children were among those killed, adding that 15 people also injured in the bombing. The reports said that the people were returning from a funeral when they came under bombing. "At least 12 civilians were killed when jets dropped shells on a convoy," a local government official told AFP, requesting anonymity. Pakistani forces have stepped up air strikes in Khyber and adjoining Pashtun tribal lands in recent months. Air strikes could undermine efforts to win over civilians for the fight against the Taliban. "Some of the families were living in the vicinity of these hideouts and they were also among the dead," said the security official. Rehan Khattak, a senior government official in Khyber, said six civilians, including women and children, were killed in one of the strikes and they had nothing to do with militants."Four people were also wounded. They were members of Kokikhel," Khattak told Reuters, referring to a pro-government Pashtun tribe which dominates Khyber. Anar Bacha, 32, one of the wounded, said they were innocent. "We are going to our home in a cab when all of a sudden planes appeared and began targeting us," he said. "We are innocent. We are Kokikhels. We are not terrorists." In April, up to 50 members of the same tribe were killed in an air raid in Tirah after they were mistaken for Taliban, prompting an apology from Pakistan army chief General Ashfaq Kayani. Khyber is a key route for U.S. and allied convoys carrying supplies for troops fighting militants in Afghanistan. Fighters frequently attack these convoys, forcing the United States to look at developing alternate routes.
