Did Israel Assassinate an Iranian Nuclear Scientist?

Israel's Mossad has a history of assassinating those they believe are a threat or have been involved in terror attacks:

A prize-winning Iranian nuclear scientist has died in mysterious circumstances, according to Radio Farda, which is funded by the U.S. State Department and broadcasts to Iran.

An intelligence source suggested that Ardeshire Hassanpour, 44, a nuclear physicist, had been assassinated by Mossad, the Israeli security service.

The Israelis have made it clear that they will do anything to prevent the Iranians from getting the bomb:

Rheva Bhalla of Stratfor, the U.S. intelligence company, 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, who have repeatedly threatened to prevent Iran acquiring the bomb.
