KABUL, Afghanistan, Ramadan 25, 1433, Aug 13, 2012, SPA - An Afghan policeman opened fire on NATO forces and Afghan soldiers Monday morning in the fifth apparent attack in a week by Afghan security forces on their international partners. The U.S.-led military coalition says none of its service members were killed. A Taliban spokesman claimed responsibility for the shooting, which took place in the eastern province of Nangarhar, saying the attacker was a police officer who had been in contact with insurgents before the assault, according to a report of the Associated Press. NATO spokesman Charlie Stadtlander says an initial investigation indicates the attacker was an Afghan police officer, though the man was wearing civilian clothes. He says the shooter escaped. --SPA 14:48 LOCAL TIME 11:48 GMT www.spa.gov.sa/1022232
