The Abu Omar Case was the abduction and transfer to Egypt of the Imam of Milan Hassan Mustafa Osama Nasr, also known as Abu Omar. The case was picked by the international media as one of the better-documented cases of extraordinary rendition carried out in a joint operation by the United States' Central Intelligence Agency (CIA) and the Italian Military Intelligence and Security Service (SISMI) in the context of the "global war on terrorism" declared by the Bush administration.
