Iran finds vital clues to N-scientist killings: Intelligence minister

“In examining the cases on identification of the perpetrators of killing the country’s nuclear scientists, we have achieved good results, the news of which will be announced,” Moslehi said in the Iranian northeastern city of Mashhad on Tuesday.

The Iranian intelligence minister also pointed to the arresting and dismantling of a terrorist cell which plotted to carry out bomb attacks in the Iranian capital, Tehran, during the Nowruz holidays (March 20-April 1), but said further details will be announced when available.

The remarks come on the same day that Iran executed Israel’s Mossad spy Majid Jamali Fashi who assassinated top Iranian nuclear physicist Massoud Ali-Mohammadi in January 2011.

Earlier on May 6, Moslehi told reporters that Iran has made important arrests, and explained that the Iranian security forces have recently identified and arrested a number of terrorists involved in the assassination of Iranian nuclear scientists.

Iran blames the US and Israel for the strings of deadly attacks against its atomic experts.

In the latest series of attacks, Mostafa Ahmadi Roshan was assassinated in January after an unknown motorcyclist attached a magnet bomb to his car in Tehran.

On November 29, 2010, Professor Majid Shahriari and Dr. Fereydoun Abbasi were targeted by terrorist attacks; Shahriari was killed immediately and Dr. Abbasi, the current head of Iran's Atomic Energy Organization, only sustained injuries.

The US, Israel and their allies accuse Iran of pursuing a military nuclear program and have used this allegation as a pretext to sway the UN Security Council to impose four rounds of sanctions on Iran to halt its nuclear work.

In November 2011, some of the US presidential hopefuls called for conducting covert operations ranging from assassinating Iranian nuclear scientists to launching a military strike on Iran as well as sabotaging Tehran's nuclear energy program.
