The U.S. military says an American soldier and two Iraqis have been killed in separate attacks in northern Iraq.

Authorities say the soldier was killed Wednesday, in a roadside bombing about 180 kilometers north of Baghdad. The two civilians died in a car bomb blast in Mosul. Fourteen others were reported wounded.

Meanwhile, Interim Iraqi Prime Minister Iyad Allawi says he is forming a broad political coalition in his uphill fight to retain his post.

Mr. Allawi, who spoke Wednesday in Baghdad, said coalition details will be released in the near future. He spoke a day after rival Shi'ite leader Ibrahim al-Jaafari was chosen by another slate for the post of prime minister.

Mr. Allawi's secular Shi'ite slate won a mere 14 percent of the vote in last month's elections, and controls only 40 seats in the country's 275-member National Assembly. In contrast, Mr. al-Jaafari's conservative slate won 48 percent and controls 140 seats.
