UN: Afghan Civilian Deaths Highest in 2009 VOA News 13 January 2010 Photo: AP A car bomb burns near a building in Kabul, Afghanistan, 15 Dec 2009 The United Nations says the number of civilians killed in war-related violence in Afghanistan reached its highest level last year since the conflict began in 2001. In a report released Wednesday, the U.N. attributes the vast majority of Afghan civilian casualties to Taliban attacks. Civilian casualties have been a sensitive subject in Afghanistan, with U.S. forces frequently accused of killing Afghan civilians in airstrikes. NATO said Wednesday an improvised explosive device killed two U.S. service members in eastern Afghanistan. In Afghanistan's southern Kandahar province, a car bomb wounded several civilians and at least two Afghan police officers. On Tuesday, the U.S. Defense Department said it has ordered more than 3,000 additional troops to Afghanistan, as part of a surge approved by President Barack Obama. A Pentagon spokesman, Bryan Whitman, said 2,600 soldiers, mostly from the Fort Hood, Texas base, will be headed to Afghanistan, accompanied by about 500 support troops. Also Tuesday, NATO denied allegations that foreign troops opened fire on demonstrators protesting the alleged desecration of the Koran in southern Helmand province. But Afghan officials in the province's Garmsir district said the clashes between security forces and protesters left at least six people dead. NATO acknowledged that troops were present at the protest, but it said an insurgent sniper was firing on the crowd. The alliance said its troops identified and killed the gunman.
