Taliban says it killed Christian aid worker

Taliban gunmen killed a Christian aid worker in Kabul on Monday that the militants accused of spreading her religion - a rare targeted killing of a Westerner in the nation's capital. Violence around the country has spiked in recent days. Gunmen kidnapped a former presidential candidate in Kabul, while a suicide bomber killed two German soldiers in the north and two operations by Afghan and NATO forces killed some 50 militants. The aid worker - a dual South African-British national - helped handicapped Afghans. Two men on a motorbike shot her with a pistol as she was walking to work around 8 a.m., said Interior Ministry spokesman Zemeri Bashary. The Taliban claimed responsibility.
