Iran's intelligence services said on Monday January 10th, that they have arrested suspects in the assassination that accrued a year ago of a nuclear physicist in a months-long covert operation that also led them to penetrate Israel's Mossad spy agency. In January 2010, Massoud Ali-Mohammadi, the nuclear scientist from Tehran University, was killed by a remote-controlled bomb attached to a motorbike parked near his house. Iran blamed the elimination on "mercenaries" in the pay of Israel and the United States. Iran's intelligence chief Heidar Moslehi did not say exactly how many people were arrested but accused "more than 10" of them of belonging to networks linked to the Israeli agency, stating that they were able to infiltrate the Zionist entity's apparatus, infiltrating deep into Mossad.
