Iran has declared that it intends to seek international action against Israel after blaming the Mossad for the murder of a nuclear scientist last year, Iran's Press TV reported on Tuesday.

"We will definitely utilize all our means and capabilities to follow up the case in international legal bodies," foreign ministry spokesman Ramin Mehmanparast said Tuesday.

Mehmanparast was referring to Tehran's recent claims that it had arrested a spy network linked to the Mossad that was allegedly involved in the 2010 assassination of of physics professor Masoud Ali Mohammadi.

The issue that we will actively pursue is the condemnation of this illegal regime [Israel] and its punishment as the perpetrator of crimes against humanity and our scientists, Mehmanparast said at his weekly press briefing on Tuesday.

Iran also condemned Western support of Israel, saying they sponsored Israel's "terror efforts.

Earlier Tuesday, Iran's intelligence chief Heidar Mosleh revealed more details about the investigation into the January 2010, saying that more than 10 suspects have been arrested and all were members of networks linked to Israel's Mossad spy agency.

Moslehi warned any nations cooperating with Israel in such plots that Iran would consider them "bases for terrorist jobs" and threats to the entire Middle East.

Iran announced Monday that it planned to probe the January 2010 assassination. The Iranian investigation report claims to have infiltrated the Mossad, uncovering additional secret plots.

Mohammadi was killed by a bomb-rigged motorcycle parked outside his house. The motives behind his assassination remain unclear, particularly in light of the fact that he had no known link to Iran's nuclear work.
