Iran 'Mossad Spy' Gets Death Sentence
Ali-Mohammadi's assassination was the first of several attacks on scientists which Iran has blamed on foreign agents.
According to taped interviews with Jamali-Fashi that appeared on Iranian television, he travelled to Turkey in search of work and became involved with the Iranian exile community in Istanbul, who in turn introduced him to the Mossad.
Two similar attacks in November killed two nuclear scientists and wounded another, Fereydoun Abbasi-Davani, who has since become Iran's atomic energy chief.
Iran's nuclear programs were further set back by the invations of the Stuxnet worm that destroyed operating systems.
