BAGHDAD, Iraq (AP) – A suicide bomber detonated an explosives-laden vehicle near the restive central city of Ramadi, killing 11 Iraqi police commandos and injuring 14 other people, including two American soldiers, the U.S. military said Friday.

The Thursday evening blast at a checkpoint on the eastern outskirts of Ramadi also wounded nine Iraqi security-force members and three civilians, bringing the total number of victims to 25, U.S. Marine Capt. Jeffrey Pool told The Associated Press.

The attacker also died in the explosion near the Sunni Triangle city of Ramadi, 70 miles west of Baghdad.

Another car bomb hit an Iraqi army convoy in Iskandariyah, 30 miles south of Baghdad, killing one soldier and injuring four others, police Capt. Muthama Abdul Rida said.

In an eastern Baghdad neighborhood late Thursday, unidentified attackers killed five female translators working for the U.S. military, police Capt. Ahmed Aboud said.

The translators “were heading home when gunmen driving two cars sprayed them with machine-gun fire,” Aboud said Friday. Further details were not immediately available.

Insurgents routinely target U.S. forces and their perceived collaborators as well as members of Iraq’s government, army and police – security forces who the U.S. military says must gain better control of the country before any major U.S. troop withdrawal.

Police found two decapitated bodies clad in Iraqi army uniforms west of Baghdad on Thursday, officials said.

The headless corpses were on the side of a road connecting Baghdad with the nearby town of Abu Ghraib, the site of the prison where U.S. troops are accused of abusing Iraqi detainees. A passing police patrol discovered them and brought them to a morgue, 1st Lt. Akram Al-Zubaai said Friday.

Army officials were not immediately available for comment.

Also near Abu Ghraib, firefighters worked Friday to extinguish an oil-pipeline blaze ignited by insurgents’ bombs, said al-Zubaai. The conduit connects Iraq’s northern oil fields with a Baghdad-area refinery.

Meanwhile, negotiators for the two biggest factions in the newly elected National Assembly were still working out details of an Iraqi coalition government that U.S. officials hope will pave the way for the eventual withdrawal of coalition forces.

The prime minister is expected to be Ibrahim al-Jaafari, a politician from Iraq’s Shiite Arab majority. Kurdish leader Jalal Talabani is likely to be named president.

Interim Deputy Prime Minister Barham Saleh told The Associated Press the next parliamentary session would be on Monday.

“Principally, we have agreed that the assembly should meet on Monday and elect the speaker and his two deputies,” he said, adding the meeting’s date was not absolutely certain.

Saleh, a Kurd, said it was not clear whether Iraq’s new president and his deputies would be announced in the same session.

One of the vice presidents will likely be a Sunni Arab, Shiite negotiators have said.

The move is an effort to reach out to the Sunni community, which is believed to be the backbone of the insurgency. Dominant under former dictator Saddam Hussein, Sunni Arabs mostly stayed away from Iraq’s Jan. 30 election, some in a boycott of the vote and others in fear of attacks.

Shiite Arabs are estimated to make up 60 percent of Iraq’s 26 million people, while Kurds and Sunni Arabs are each thought to be 15 percent to 20 percent.
