Firouzabadi noted that the enemy's intelligence and spy agencies are acting in unison against Islam.

"A glance at the historical background of the global arrogance and Zionism shows that the intelligence agencies of Europe and other countries that are under the yoke of colonial rule are controlled by Mossad and the will of the Zionist leaders," he added.

Firouzabadi said that the tremors of the 1979 Islamic Revolution put the Zionists in such a condition that they saw their deaths before their eyes.

His remarks came after a new book by US-Israeli journalists admitted that Mossad agents carried out assassination of Iranian scientists, saying that the killings were too sensitive for Mossad to share with foreign freelancers.

In "Spies Against Armageddon: Inside Israel's Secret Wars," (Levant Books), CBS News national correspondent Dan Raviv and former intelligence correspondent Yossi Melman wrote that the Mossad operates a special secret unit in called Kidon, Hebrew for bayonet.

The book claims that contrary to reports linking the killings to Iranian dissidents working for Israel, it is very unlikely that Israel would have contracted out such sensitive operations through a third party dissident group.

"The methods, communications, transportation, and even the innovative bombs used in the Tehran killings are too sensitive for the Mossad to share with foreign freelancers," Raviv and Melman wrote.

Late in June, Iran announced that its intelligence forces had identified and arrested all terrorist elements behind the assassination of the country's nuclear scientists.

"All the elements involved in the assassinations of the country's nuclear scientists have been identified and arrested," Iran's Intelligence Ministry announced in a statement late last month.

A number of countries, whose territories and facilities had been misused by the Mossad-backed terrorist teams, have provided the Iranian officials with relevant information, the statement added.

Over the course of the investigations, all other elements behind the assassinations of the Iranian scientists Massoud Ali-Mohammadi, Majid Shahriari and Mostafa Ahmadi Roshan as well as Reza Qashqaei (Roshan's driver) have been apprehended, the statement read.

Some of the perpetrators of the assassination of Dr. Fereydoun Abbasi, the current head of Iran's Atomic Energy Organization, are among those arrested, the ministry added.

According to the statement, Iran's Intelligence Ministry has detected some of Mossad's bases within the territories of one of Iran's Western neighbors, which provided training and logistic support to the terrorist networks.

In the fifth attack of its kind in two years, terrorists killed a 32-year-old Iranian scientist, Mostafa Ahmadi Roshan, and his driver on January 11.

The blast took place on the second anniversary of the martyrdom of Iranian university professor and nuclear scientist, Massoud Ali Mohammadi, who was also assassinated in a terrorist bomb attack in Tehran in January 2010.

The assassination method used in the bombing was similar to the 2010 terrorist bomb attacks against the then university professor, Fereidoun Abbassi Davani - who is now the head of Iran's Atomic Energy Organization - and his colleague Majid Shahriari. While Abbasi Davani survived the attack, Shahriari was martyred.

Another Iranian scientist, Dariush Rezaeinejad, was also assassinated through the same method on 23 July 2011.
