It caused shock and some anger in Iraq and elsewhere, now the US says it is to investigate the publication of photos of Saddam Hussein in his underwear.The Pentagon has condemned the release of the pictures which appeared in a British tabloid newspaper and says it will track down and punish those who took them. President George Bush has also spoken out against the publication of the images which has been described as a violation of the Geneva Convention. The Sun newspaper says it got them from a military source. They have been published in the New York Post as well. The incident is likely to heighten hostility towards the US in some muslim nations where there is already anger over a news report of desecretation of the Koran. The claim that a copy of the Islamic holy book had been flushed down a toilet at the Guantanamo Bay detention centre caused protests in several countries.
