September 17, 2008 US Defense Secretary Expresses Regret for Afghan Civilian Deaths ---------------------------------------------------------------- http://enews.voanews.com/t?ctl=1E3CA9D:A6F02AD83191E160BAE77F07E736558CB3350E090FE6A6E8& Robert Gates says he offered all Afghanistan his 'sincere condolences' for recent loss of innocent life as result of coalition airstrikes US Secretary of Defense Robert Gates delivers a speech at the U.S. Embassy in Kabul, 17 Sep 2008The U.S. defense secretary has expressed "personal regret" for civilians killed by U.S. airstrikes in Afghanistan. Robert Gates said in Kabul Wednesday that he offered all Afghanistan his "sincere condolences" for the recent loss of innocent life as a result of coalition airstrikes. Gates said the U.S. military makes every effort to avoid civilian casualties, but he added that the military has to work even harder. Afghanistan's government and people have expressed anger with the U.S. military about the increasing number of civilians killed during attacks on militant targets. Gates earlier discussed the situation with Afghan President Hamid Karzai. Separately Wednesday, the U.S.-led coalition said a roadside bomb killed four soldiers and an Afghan national in the country's east. It did not identify the troops' nationalities, or say where exactly the explosion happened. Most foreign troops serving under the coalition in eastern Afghanistan are from the United States. The troops have been working with the Afghan army to fight Taliban militants since 2001, when a U.S.-led invasion pushed the Taliban from power. The top U.S. and NATO commander in Afghanistan, General David Mc Kiernan, said Tuesday that 10,000 more troops are needed to fight the Taliban, in addition to the U.S. combat brigade due to arrive in January.
