About 1,000 backers of an anti-American Shiite cleric staged a protest Monday in Baghdad demanding Israel immediately stop its air assault on the Gaza Strip.
The supporters of cleric Muqtada al-Sadr chanted "No, no to Israel" and burned Israeli and American flags during the demonstration in eastern Baghdad.
A top aide to al-Sadr, Imam Abdul Hadi al-Mohammadawi, told the crowd that the world knows about "the bloody history of Israel" and the "horrible crime" it is committing in Gaza.
Separately, the political party of Iraqi Prime Minister Nouri al-Maliki issued a statement condemning the attacks and calling on Islamic countries to cut relations with Israel and end all "secret and public talks" with it.
The al-Dawa party "is calling on Muslim people to stand beside these oppressed people (and) is calling on all Palestinian commands to unite their position against this aggression."
Israel's airstrikes on the Gaza Strip have sparked outrage in the Middle East. About 300 Palestinians have been killed since air assault began Saturday.
Also Monday, an Iraqi security official told The Associated Press that a guard in the prime minister's convoy accidentally fired his machine gun, killing one Iraqi soldier and wounding three others.
The incident occurred Saturday on the outskirts of Baghdad as al-Maliki was traveling to Karbala, the official said on condition of anonymity because he was not authorized to speak with news media.
The official said the guard was in the lead car of the convoy when he accidentally fired his weapon, hitting a military vehicle ahead of him. The incident is under investigation.
The U.S. military said in a statement that it had received reports from its Iraqi military liaison of an Iraqi soldier killed by fire from an unidentified convoy, but did not have further information.
