The Danish editor behind the publication of caricatures of the Prophet Mohammad that ignited deadly riots in the Muslim world, said Wednesday that he was trying to coordinate with an Iranian paper soliciting cartoons on the Holocaust.

"My newspaper is trying to establish a contact with the Iranian newspaper, and we would run the cartoons the same day as they publish them," Flemming Rose said Wednesday in an interview on CNN's "American Morning."

The Iranian newspaper Hamshahri said Tuesday that it would hold the competition to test whether the West extended the principle of freedom of expression to the Nazi genocide as it did to the caricatures of the Prophet Mohammad.
