Iran says 10 suspected killers linked to Mossad

Iran's intelligence chief is revealing more details about the investigation into last year's killing of a nuclear physicist. He says more than 10 suspects have been arrested and all were members of networks linked to Israel's Mossad spy agency.

Heidar 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. He spoke to reporters Tuesday.

On Monday Iran announced its probe into the January 2010 slaying of physics professor Masoud Ali Mohammadi had led its agents to infiltrate the Mossad and uncover other plots.

Mohammadi was killed by a bomb-rigged motorcycle parked outside his house. Possible explanations have never been clear, particularly as he had no known link to Iran's nuclear work.
