A suicide bomber walked up to a checkpoint and blew himself up near a major Pakistan Air Force base Friday, killing at least six people and wounding another nine, police said. At least seven people were killed and 13 wounded in a suicide attack on a military base in Kamra near the Pakistan Aeronautical Complex (PAC), a private TV reported Friday. The incident took place in the town of Kamra, some 80 kilometres (50 miles) west of Islamabad near the Pakistan Aeronautical Complex (PAC). "It was a suicide attack, which killed six people including four civilians and two Pakistan Air Force personnel," district police chief Fakhar Sultan told media. Nine people were also wounded in the attack, he added. The identities of the wounded were not immediately clear. The attacker blew himself up when he was stopped at a security checkpoint on the main road used by both civilians and air force personnel, Sultan said. "We have found a mutilated face, as well as other body parts, including legs and arms of the bomber," he said.
