A scientist involved in Iran's nuclear program died two weeks ago in mysterious circumstances said to be connected with the Mossad, the Sunday Times has reported. According to the report, an American source hinted that the prize-winning scientist, Prof. Ardshir Hassanpour, 44, was assassinated by the Mossad. His death was reported on January 21, six days afterwards. At the time, his death was attributed to gas poisoning. The report first surfaced when announced by US-funded Iranian radio station, Radio Farda. Hassanpour was said to have worked at the Isfahan nuclear technology center, in which uranium hexafluoride gas is produced. Once uranium gas is produced in Isfahan, it is taken to the Uranium Enrichment Plant in Natanz, central Iran. According to the Iranian radio station, the Iranian reports did not say how or where Hassanpour was poisoned, but his death was said to have been announced at a conference on nuclear safety. "A US intelligence company," the Times report read, claimed on Friday that "Hassanpour had been targeted by Mossad and that there was very strong intelligence to suggest that he had been assassinated by the Israelis."
