Hassan Mustafa Osama Nasr, also known as Abu Omar, is an Egyptian cleric. In 2003, he was living in Milan, Italy, from where he was kidnapped and tortured in Egypt. This "Imam rapito affair" prompted a series of investigations in Italy, culminating in the criminal convictions of 22 CIA operatives, a U.S. Air Force colonel, and two Italian accomplices, as well as Nasr, himself.

Extraordinary rendition is a euphemism for state-sponsored kidnapping in another jurisdiction and transfer to a third state. The phrase usually refers to a United States-led program used during the War on Terror, which had the purpose of circumventing the source country's laws on interrogation, detention, extradition and/or torture. Extraordinary rendition is a type of extraterritorial abduction, but not all extraterritorial abductions include transfer to a third country.
