Iraqi national guardsmen backed by U.S. troops have raided a prominent Sunni Muslim mosque in Baghdad, making several arrests and killing at least two people.
No reason has been given for the raid, but the Abu Hanifa mosque is known for its anti-American agitation and support for the former regime of Saddam Hussein.
On Thursday, the Iraqi interim government warned that Islamic clerics who incite violence will be considered participants in terrorism.
Meanwhile, in central Baghdad, a suicide car bomber killed a policeman and at least one bystander, while injuring nearly a dozen other people near an Iraqi police patrol.
And the aid group World Vision Australia says it is pulling out of Iraq because it is too dangerous for its staff to remain.
The decision follows the apparent murder of CARE International aid official Margaret Hassan.
