Iran makes arrests in nuclear scientist’s assassination

Iran’s state news service, the Islamic Republic News Agency, said the killers had been identified.

Iranian nuclear scientist Mostafa Ahmadi Roshan was killed last week in Tehran after a motorcyclist placed a bomb under his car, the latest in a series of assassinations of Iranian nuclear officials in the past two years.

Iran’s supreme leader Ayatollah Ali Khamenei blamed the CIA and Mossad, Israel’s intelligence agency, for the killing.

Senior U.S. officials have categorically denied any role in the assassination, while Israeli officials have not issued similar denials.

The United States, Israeli and other Western allies say Iran is trying to develop a nuclear weapon, while Iran says its nuclear program is for peaceful purposes like energy production.
