Iraq's ruling Shi'ite alliance has chosen incumbent Prime Minister Ibrahim al-Jaafari to head the new government.

He received 64 votes in the caucus of Shi'ite legislators, beating his rival, Vice President Abel Abdul-Mahdi by one vote.

The Shi'ite alliance won a majority in Iraq's December legislative election.  Naming the prime minister is a key step in forming a new Iraqi government, the nation's first post-Saddam Hussein parliament with a four-year mandate.

Separately, Iraqi police say at least 12 people were wounded today when two roadside bombs exploded in quick succession near a restaurant in central Baghdad.

Also, the U.S. military says insurgents fired a mortar round Sunday into the heavily fortified Green Zone, home to the U.S. Embassy and Iraqi government.  There were no reports of casualties.
