The U.S. military said six of its troops were in stable condition after their convoy was hit by a roadside bomb on Sunday in the eastern province of Kunar, where 19 U.S. troops were killed in clashes with insurgents last month.
News of the latest attack in Kunar came after the military announced earlier that one U.S. soldier was killed and another wounded in an insurgent attack in the southern province of Helmand early on Sunday.
The attacks came amid stepped up militant violence in Afghanistan ahead of Sept. 18 parliamentary elections in which hundreds of people have died.
