The U.S. military in Iraq says American and Iraqi forces have killed 15 suspected al-Qaida militants in a daylong battle south of Baghdad.

The military said Tuesday the fighting happened Monday in the town of Adwaniyah. It says up to 45 al-Qaida gunmen in trucks and on foot attacked checkpoints set up by local residents who recently began working with U.S. troops.

The U.S. military says the local security guards repelled the attackers with help from U.S. and Iraqi forces. It says American F-16 fighter jets dropped two large bombs in the area during the battle.

The U.S. military has recruited thousands of Iraqi citizens to run checkpoints and guard infrastructure in and around Baghdad. U.S. commanders say the local security guards have helped reduce violence in recent months.
