A United Nations investigation found Afghan security forces may have mistakenly killed four U.N. staff members in Kabul last October, AP reported. U.N. peacekeeping field support chief Susana Malcorra said Monday that a fifth U.N. official burned to death when three suicide attackers stormed a Kabul guest house and set fire to the building. Three Afghan security officers and the three assailants also died during the Oct. 28 incident. Malcorra said the attackers were wearing the same Afghan police uniforms as the security staff at the guest house where 34 U.N. staff lived. After the attack the U.N. sent about 600 of its 1,100 foreign staffers out of the country or into more secure quarters.
