MOSSAD AND IRAN

A new book has identified the Israeli spy agency, Mossad, as the culprit in the assassination of at least four Iranian nuclear scientists as part of a campaign to sabotage Iran's nuclear energy program.

In their book, entitled Spies Against Armageddon: Inside Israel's Secret Wars, CBS national correspondent Dan Raviv and Israeli journalist Yossi Melman said that Israeli spies have killed at least four Iranian nuclear scientists.

The Mossad agents are well-trained in shooting and placing “exquisitely shaped sticky bombs" and consider it their hallmark, the Associated Press quoted Raviv as saying on Friday.

The book also says the assassinations were part of a campaign aimed at preventing Iran from developing its nuclear energy program.

"They don't farm out a mission that is that sensitive," so sensitive that Israel's prime minister has to sign off on it personally, Raviv said.

"They might use dissidents for assistance or logistics but not the hit itself. The methodology and training and use of motorcycles is all out of the Mossad playbook. They wouldn't trust anybody else to do it."

Iran had already announced that Iranian scientists Mostafa Ahmadi Roshan, Daryoush Rezaeinejad, Professor Majid Shahriari, and Professor Masoud Ali-Mohammadi were all assassinated by Israeli agents.

Ahmadi Roshan and his driver (Reza Qashqaei) were assassinated in January 2012 after a motorcyclist attached a magnetic bomb to their car in Tehran.

On July 23, 2011, gunmen killed Rezaeinejad outside his house in Tehran. Rezaeinejad and his wife were on their way to their child's kindergarten when they were approached by two men on a motorbike. The gunmen called him by name and shot Rezaeinejad, 35, in the neck when he turned around.

On November 29, 2010, terrorists attached bombs to the vehicles of Iranian university professors Majid Shahriari and Fereydoun Abbasi and detonated the explosives. Professor Shahriari was killed immediately, but Dr. Abbasi and his wife only sustained minor injuries.

Professor Ali-Mohammadi, a lecturer at Tehran University, was killed by a booby-trapped motorbike in the Iranian capital in January 2010. The bombing took place near the professor's home in the Qeytariyeh neighborhood of northern Tehran.
