Hassan Mustafa Osama Nasr (Arabic: ??? ????? ????? ???? ?assan Mu??afa Usamah Na?r) (born 18 March 1963), 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 (in absentia) of 22 CIA operatives, a U.S.
Air Force colonel, and two Italian accomplices, as well as Nasr, himself.
