Afghan Taliban Claim Responsibility Attack on US Intel Workers VOA News 31 December 2009 Protestors in Kabul Photo: AP Afghans chant anti American slogans in Kabul, Afghanistan during a protest against the recent killings of 10 civilians allegedly by coalition forces in Kunar province, 30 Dec 2009 Italicize The Taliban has claimed responsibility for a suicide blast in eastern Afghanistan that killed eight Americans Wednesday. Employees of the U.S. Central Intelligence Agency are reported to be among the dead. Taliban spokesman Zabiullah Mujahid said Thursday that the attack on a U.S. base in Khost province was carried out by an Afghan army officer working for the militants. U.S. officials said the bomber got inside the base - Forward Operating Base Chapman - before he detonated his explosive vest near the facility's gym. Current and former U.S. officials say some of the victims were CIA officers, while the others may have been civilians working for the American intelligence agency. At least six other people were wounded, some severely. The CIA has not commented on the incident. The agency has been increasing its presence in the region over the past year in advance of the U.S. troop surge, helping launch drone attacks on al-Qaida and Taliban positions along the Afghanistan-Pakistan border. The site of Wednesday's suicide attack, Khost, borders Pakistan's North Waziristan tribal region, which has served as a base of operations for Taliban militants and their allies. Afghan officials claim more civilians have been killed, the reuslt of a foreign airstrike in the country's Helmand province. Officials say the air strike took place Wednesday, near the provincial capital of Lashkar Gah. Witnesses say at least eight civilians were killed. Earlier Wednesday, the Afghan government charged foreign troops killed 10 civilians - including school children - in eastern Afghanistan's Kunar province on Sunday. But a spokesman for international troops in Afghanistan says NATO so far has no direct evidence to support the allegation. NATO released a statement Wednesday saying its forces were targeting insurgents when troops came under fire. The alliance says nine people were killed when NATO forces returned fire. Hundreds of university students took to the streets in Kabul and in the eastern city of Jalalabad Wednesday to protest the killings. In a separate incident Wednesday, the Canadian defense ministry says four Canadian soldiers and a Canadian journalist were killed when their convoy hit a roadside bomb while on patrol just outside the southern city of Kandahar. The journalist was identified as 34-year-old Calgary Herald reporter Michelle Lang. A Canadian civilian official was wounded in the blast. The Canadian newspaper says Lang is the first Canadian journalist to die in the Afghan war since Canada joined the international mission in 2002.
