Iran Says Busts 'Terrorist Groups' Behind Assassination of Nuclear Scientists

Islamic Republic's Intelligence Ministry claims 20 suspects arrested in operation to locate killers of Majid Shahriari Mostafa Ahmadi Roshan, assassinated in the last 2 years.

Iran has arrested 20 suspects linked to the assassination of two nuclear scientists in the last two years, a statement by Tehran's Intelligence Ministry claimed on Sunday.

The statement came after, on Thursday, the Intelligence Ministry issued a preliminary report concerning the arrests, saying only that the "details of the arrest will be made public after lapse of security precaution."

Iranian officials indicated to Fars that those arrested were involved in the assassination of nuclear scientists Majid Shahriari, who was killed in late 2010 and Mostafa Ahmadi Roshan, targeted earlier this year.

On Sunday, the official IRNA Iranian news agency cited a statement by Iran's Intelligence Ministry, saying that 20 suspects had been arrested, and that preliminary investigations pointed at "two terrorist groups."

A Fars report from 2010 claimed that Shahriari was assassinated after a bomb was attached to his car by assassins on motorcycles, with Interior Minister Mostafa Mohammad-Najar accusing the U.S. and Israeli intelligence services of carrying out the attack.

"The CIA and Mossad have always been the enemies of Iran and constantly tried to sabotage our technological progress," he told state television.

On January of this year, Iranian media reported that Roshan, a supervisor at the Natanz uranium enrichment facility, was also reportedly killed after a bomb was placed on his car by a motorcyclist in Tehran.
