Egyptian cleric Hassan Mustafa Osama Nasr, also known as Abu Omar, shows what he says is a scar on his arm, at a court house in Alexandria, Egypt in this February 22, 2007 file photo. Italian judge Oscar Magi could decide on May 14 to make Silvio Berlusconi the first head of a government to testify in criminal proceedings over secret CIA transfers of terrorism suspects. The judge is expected to announce his decision on whether to call Berlusconi and other politicians when he resumes a trial against 26 Americans and seven Italians accused of carrying out a transfer or "rendition" in 2003. Prosecutors say a CIA-led team kidnapped cleric Nasr off the streets of Milan and secretly flew him to Egypt. There, the terrorism suspect says he was tortured under questioning and held for years without charge.
