Mordechai Vanunu (also known as John Crossman) is an Israeli former nuclear technician and peace activist, who, citing his opposition to weapons of mass destruction, revealed details of Israel's nuclear weapons program to the British press in 1986. He was subsequently lured to Italy by the Israeli intelligence agency Mossad, where he was drugged and abducted.He was secretly transported to Israel and ultimately convicted in a trial that was held behind closed doors.
Vanunu spent 18 years in prison, including more than 11 in solitary confinement, though no such restriction is mentioned in Israel's penal code, nor imposed by his verdict. Released from prison in 2004, he was further subjected to broad array of restrictions on his speech and his movement, and arrested and imprisoned several times for violations of his parole terms, giving interviews to foreign journalists and attempting to leave Israel. He claims having suffered "cruel and barbaric treatment" at the hands of prison authorities, and suggests that these would have been different if he had not converted to Christianity.
