In 2007, Vanunu was sentenced to six months in prison for violating terms of his parole. The sentence was considered unusually severe even by the prosecution, who expected a suspended sentence. However, in May 2010, Vanunu was arrested again and sentenced to three months in jail on a charge that he had met foreigners, in violation of conditions of his 2004 release from jail. In response, Amnesty International issued a press release on July 2007, stating that "The organisation considers Mordechai Vanunu to be a prisoner of conscience and calls for his immediate and unconditional release."
