KHALIS, Iraq, May 29, 2 A roadside bomb hit a bus carrying Iraqi workers on Monday, killing 11 people and wounding another 11 in a small town northeast of Baghdad, police said.

The bomb exploded soon after the bus had left the station in Khalis, taking about 44 workers to jobs at the nearby Camp Ashraf, the home of the Mujahedeen e-Khalq, an Iranian movement once supported by ousted dictator Saddam Hussein which was seeking to overthrow the clerical government in neighboring Iran.

The movement has since been disarmed and confined to its camp by US forces.

The mixed Sunni-Shiite province of Diyala northeast of Baghdad has been been wracked by violence -- usually with sectarian overtones -- directed against civilians, with a major surge in attacks in the past week.

In southern Baghdad, a another bomb went off inside a commuter minibus, killing two Iraqis and wounding one. In the middle-class neighborhood of Karrada, a blast killed one person and injured three others, hospital officials said.

A policeman in Amara, south of Baghdad, was killed when assailants crept into his house under the cover of night and stabbed him to death.

Just southeast of the capital, in Wasit province, a total of nine corpses were discovered Sunday night.
