Security agents have broken the arm and ribs of al-Zaidi, a reporter who hurled his shoes at Bush during a press conference Sunday in Baghdad.

"He has got a broken arm and ribs, and cuts to his eye and arm," the reporter's brother Durgham told AFP on Tuesday.

"He is being held by forces under the command of Muaffaq al-Rubaie," he added.

According to Durgham, his brother was being held by Iraqi forces in the heavily fortified Green Zone compound in central Baghdad.

On Monday, thousands of Iraqis staged a demonstration in Sadr City in Baghdad calling for the release of the journalist.

The 29-year-old Muntadhar al-Zaidi, a correspondent for al-Baghdadiya satellite channel, threw his shoes at the US President George W. Bush during a press conference on Sunday, shouting "This is a goodbye kiss from the Iraqi people, dog!"

Bush inked an interim security agreement with Iraqi Prime Minister Nouri al-Maliki during his farewell visit to Baghdad in a bid to extend the presence of US troops in the war-ravaged country.
