Two suicide bombers wearing police uniforms blew themselves up inside the police headquarters of Paktika province in southeastern Afghanistan on Saturday, killing at least 10 officers and wounding 13 others, according to NATO officials and the emergency physician on duty at the hospital where some victims were taken. Nine wounded officers were taken for medical treatment to a NATO base, Forward Operating Base Lightning, in neighboring Paktia province. While suicide bombings occur almost every week in Afghanistan, the majority have missed their targets and either killed the bomber or civilians. Saturday's bombing, however, appeared to have been more carefully planned and executed. A former member of parliament from Paktika province, Pir Sayed Ishaq Gilani, said he thought it was possible that the bombers could have been police officers themselves. 'When a person gets hired as a policeman that person does not get screened properly,' Gilani said. 'The police headquarters does not ask him about his background and about his family; they just hire him, and then those types of people can cause big problems in the future.' The attackers, their explosives concealed by the uniforms, walked into the headquarters in Sharan, the provincial capital, at midday and detonated their bombs as officers were milling around just before the lunch hour. Paktika, a province that borders the Taliban and insurgent stronghold of South Waziristan in Pakistan's federally administered tribal areas, has been troubled for months as Taliban and NATO forces battle for influence there. Although NATO has repeatedly released statements announcing the repulsion of Taliban forces and the commitment of tribal elders to supporting the Afghan government, the area has continued to be vulnerable to attacks, suggesting that local support for insurgents remains. Parliament members, including Gilani, said that many local people have been detained by NATO and Afghan forces. In several cases, they said, those detained were not involved in the insurgency and their arrests added greatly to the resentment of the government and Western forces. Also on Saturday, a NATO service member died in an improvised explosive device attack in eastern Afghanistan.
