KABUL, Afghanistan (AP) — A series of clashes and an airstrike in southern Afghanistan killed 25 militants and eight civilians held hostage by insurgents, the U.S.-led coalition said in a statement today.

Militants ambushed the coalition and Afghan troops along a road in the southern province of Uruzgan on Sunday, triggering gunbattles during which militants moved into a compound and took 11 civilians hostage, the statement said.

“Coalition troops called in close-air support to engage the militants hiding in the structure. They did not have knowledge of noncombatants in the buildings at that time,” the coalition statement said.

As a result, eight civilians were killed and three were wounded, the coalition said. The wounded civilians were taken to a coalition base for treatment.

U.S. 1st Lt. Nathan Perry, a coalition spokesman, said three civilian hostages survived the airstrike in Khas Uruzgan district, including an infant, a man in his 40s and a woman in her 20s.
