The BBC:

“The brother of the Iraqi journalist who threw his shoes at US President George W Bush has said that the reporter has been beaten in custody.

Muntadar al-Zaidi has suffered a broken hand, broken ribs and internal bleeding, as well as an eye injury, his older brother, Dargham, told the BBC.
Mr Zaidi threw his shoes at Mr Bush at a news conference, calling him “a dog”.

The head of Iraq’s journalists’ union told the BBC that officials told him Mr Zaidi was being treated well.

The union head, Mouyyad al-Lami, said he hoped to visit his colleague later.
An Iraqi official said Mr Zaidi had been handed over to the judicial authorities, according to the AFP news agency.

Earlier, Dargham al-Zaidi told the BBC’s Caroline Wyatt in Baghdad he believed his brother had been taken to a US military hospital in the Iraqi capital.

A second day of rallies in support of Mr Zaidi have been held across Iraq, calling for his release.
Meanwhile, offers to buy the shoes are being made around the Arab world, reports say.”

According to a senior level commander on the ground with knowledge of where Mr. Zaidi is being held the charge is false and Mr. Zaidi is being treated “extremely well”.

Obviously his brother is trying to further inflame the Arab flames and increase the pressure to release his brother.

But other than his word there is absolutely no confirmation or truth to the allegation.
