Coalition forces killed 10 militants in a strike against a bomb-making cell in eastern Afghanistan, US forces said Saturday. The troops were targeting several key figures in a network run by Jalaluddin Haqqani, a militant leader believed to operate out of Pakistan, the US military said in a statement. Several groups of armed militants fired on the coalition troops during the operation Friday, according to the statement. The coalition forces returned fire, killing their attackers and destroying a weapons cache, it said. Separately, Afghan police said two national intelligence agents and one police officer were killed late Friday in a bomb attack on their vehicle south of Kabul. They were hit while responding to an earlier bomb attack that injured three police officers, regional police commander Gen. Zalmai Oryakhail said.
