Afghan President Hamid Karzai condemned a U.S. operation he said killed 16 Afghan civilians, while hundreds of villagers denounced the American military during an angry demonstration Sunday. Karzai said the killing of innocent Afghans during U.S. military operations "is strengthening the terrorists." He also announced that his Ministry of Defense sent Washington a draft technical agreement that seeks to give Afghanistan more oversight over U.S. military operations. The same letter has also been sent to NATO headquarters. Karzai in recent weeks has increasingly lashed out at his Western backers over the issue of civilian casualties, even as U.S. politicians and a top NATO official have publicly criticized Karzai for the slow pace of progress here.
