Iran blames the Mossad for the slaying of Tehran University physics professor Masoud Ali Mohammadi in a January 2010 bomb blast in Tehran.
A secret service statement read out on state TV Monday said its agents have also acquired key information about Mossad plots against Iran that it will detail later.
Iran has also accused Israel and the West of being behind a pair of bomb attacks that killed one nuclear scientist and wounded another in Tehran in November.
Iran says the attacks were part of a covert Western campaign to sabotage its nuclear program.
