Iran's Judiciary on Sunday sentenced Ali Jamali-Fashi, who assassinated nuclear physicist Massoud Ali-Mohammadi in 2010, to death, the semi-official Mehr news agency reported.
Judiciary spokesman Gholam-Hossein Mohseni-Ejei made the announcement in an interview, said the report.
Dr. Ali-Mohammadi, a professor of Tehran University, was killed by a remote control bomb attached to a motorbike near his home in northern Tehran in January 2010.
The trial session of the defendant was held on Aug. 23, when Jamali-Fashi said he had some links with the Israeli intelligence agents in the assassination plot of the Iranian scientist.
Iran has accused Israel of assassinating its nuclear scientists, and has blamed the United States for being behind the terror acts against Iranian scholars.
The West suspects that Iran's uranium enrichment may be meant for producing nuclear weapons. Iran denied the accusation, saying its nuclear program is only for peaceful use.
