The U.S. military in Iraq says coalition forces have killed eight al-Qaida terrorists in a raid near the city of Baqouba, north of Baghdad.

The military says troops called in air support after coming under heavy fire during a raid to detain a known insurgent cell. It says two Iraqi women also were killed in the clash.

Separately, one U.S. soldier was killed in fighting in al-Anbar province.

In other violence Wednesday, insurgent attacks in and near the northern city of Samarra killed six police officers.

In Baghdad, a bomb killed two people near a major bus station and gunmen attacked a government ministry without causing casualties.

Meanwhile, the U.S. military says coalition forces have captured 11 suspected senior-level members of the Ansar al Sunna terrorist group this month.

In other developments, the U.N. Security Council Tuesday voted unanimously to extend the mandate of the U.S.-led multinational force in Iraq through the end of next year.

The vote was in response to a recent request for an extension of the forces' mandate from Iraqi Prime Minister Nouri al-Maliki.
