In Iraq, at least 2 US soldiers were killed today in separate attacks after their convoys were hit by roadside bombs in Baghdad.

One soldier from Task Force Iron Horse died and four others were wounded when a bomb exploded this morning in the center of Baqouba, just north of Baghdad.

The deaths brought the number of US soldiers killed in combat since Washington invaded Iraq in March to at least 543.

Meanwhile in the Iraqi city of Fallujah, 17 Iraqi police officers and at least four civilians were killed over the weekend in a series of coordinated attacks by gunmen on three police stations, a civil defense base and the mayor’s office. At one of the police stations, up to 87 prisoners were freed. Four of the attackers died in the raids. Iraqi and U.S. officials claimed two of the dead attackers were Lebanese and one was Iranian. The attack raised new concerns over the strength of Iraq’s police forces. Over the past week 125 Iraqis have died in attacks on army and police stations.

On Sunday Iraqi police arrested former Ba’thist member Muhammad Zimam. He was number 41 on the U.S. most wanted list.
