Iran said Monday it has dismantled an Israeli spying network and arrested a group of its terrorist-spies who were linked to the assassination of its nuclear scientist.

According to an announcement by Iran's Intelligence Ministry, the Iranian security forces arrested the elements of the terror attack on Iran's nuclear scientist, Dr. Massoud Ali-Mohammadi, and annihilated the "spying and terrorist network of the Zionist regime" of Israel linked to the assassination, Iranian state IRINN TV reported.

The announcement said that "In order to carry out its non-human, anti-Islamic and anti-Iranian wills, the Mossad (Israeli intelligence agency) has used its bases in some European, non- European and some neighboring states of the Islamic Republic to conduct the terror attack against Dr. Massoud Ali-Mohammadi," according to the TV report.

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.

Following clever security operations, Iran finally succeeded in arresting the main agents behind the terrorist incident and dismantled a network comprising of spies and terrorists commissioned by Israel, an Intelligence Ministry announcement was quoted as saying by local satellite Press TV on Monday.

The announcement was also quoted as saying by IRINN that in the near future the detailed information concerning the arrests will be issued.

In the meantime, Iranian lawmaker Esmail Kowsari said Monday that the assassins of Ali-Mohammadi were trained by the Israeli intelligence agency Mossad, the local Fars news agency reported.

"Long before the assassination of Ali-Mohammadi, the intelligence officials of Israel, the UK and the U.S. had publicly threatened to kill our nuclear scientists," Kowsari was quoted as saying by Press TV.

"They (the assassins) have confessed that they were trained for terror acts by Mossad and all the (terror) equipment were given to them by Mossad," Kowsari, member of National Security and Foreign Policy Commission of Iranian Majlis (parliament), said according to Fars.

"Due to the confessions of the assassins of Ali-Mohammadi, the judiciary system of the country will punish them soon," said Kowsari.

In November 2010, another Iranian nuclear scientist Majid Shahriar was also killed by a bomb attached to his car on the way to his work.

Iranian authorities has been accusing the United States and Israeli intelligence services of behind the assassinations.
