Baghdad ? Two U.S. soldiers were killed in a pair of roadside bombings over the weekend, the U.S. military announced Monday.

One soldier died in a bomb blast Sunday night in Salahuddin province, north of Baghdad, which left two other soldiers wounded, the military said. No further information was provided.

The province has a predominantly Sunni Arab population. Many Sunnis who fought Americans in the past have formed an alliance with the U.S. military in the past year, but other Sunni fighters, often affiliated with al-Qaida in Iraq, have continued to fight U.S. forces.

The second bombing occurred Sunday afternoon in Qadisiya province in southern Iraq. One soldier was killed and two others wounded when the blast ripped into a patrol just west of the province’s capital, Diwaniya, the military said.
