The U.S. military said nine suspected militants have been killed in separate operations in southern and central Afghanistan.
It said U.S.-led coalition forces killed two militants and captured six others in a clash Thursday in the southern province of Helmand.
Separately, the military said seven militants were killed during an airstrike that followed a gunbattle in the central province of Ghazni Wednesday. It also said a Taliban commander was detained.
U.S. President Barack Obama has ordered 21,000 additional troops to reinforce the 38,000 U.S. troops already in Afghanistan, where the Taliban-led insurgency is spreading.
