A suicide car bomber in the Iraqi capital has struck a convoy carrying an elite Iraqi police unit, killing at least nine people, most of them anti-terror commandos.
Authorities say at least 10 others were wounded in the attack.
The bombing followed clashes overnight in Baghdad between U.S. troops and militiamen loyal to Shi'ite cleric Moqtada al-Sadr. Coalition authorities say U.S. troops killed at least eight militiamen and wounded five others, as they sought to detain a group of fighters suspected of carrying out guerrilla attacks.
Elsewhere in Baghdad, police say gunmen raided a convoy of armored vehicles, killing two guards and stealing $850,000.
To the south, a bomber on a bicycle blew himself up in a crowded market in Hilla, killing at least one other person and wounding dozens of others.Some information for this report provided by AP and Reuters.
