KABUL (AP) — A battle in western Afghanistan that included airstrikes killed dozens of Taliban militants after an insurgent ambush left three U.S. troops dead, an Afghan official said Sunday. The hours-long battle took place Saturday in the western province of Farah after a complex attack killed three Americans and seven Afghan troops, said Afghan army spokesman Maj. Abdul Basir Ghori. The insurgent ambush involved two roadside bombs, gunfire and rocket-propelled grenades, Capt. Elizabeth Mathias, a U.S. military spokeswoman, said Sunday. Mathias confirmed that fighting in the west continued for six to eight hours after the ambush, but could not provide any casualty figures. “The combined ISAF and Afghan force was receiving significant small-arms, RPG and indirect fire throughout that time frame,” she said, referring to the NATO-led International Security Assistance Force.—-Contact The Daily Reveille’s news staff at [email protected]
