Insurgency attacks have declined for the first time in five months, with a 29 percent reduction in Helmand province, where the United States is expected to halve troop presence in the next six months, the Pentagon report said.
A major concern, the report said, is whether the Afghan government, hampered by corruption and lack of training, can hold onto the gains made by U.S. troops in the past three years.
"Setbacks in governance and development continue to slow the reinforcement of security gains," the report said.
Afghan protesters rallied against American troops Tuesday, protesting the death of three children during a battle between U.S.-led forces and the Taliban, The Washington Post reported.
