Several people, cooperating with the Israeli Ron Arad Foundation, were arrested in Iran, FARS news agency quotes the Iranian Defense Minister Heidar Moslehi, as saying.
Moslehi said that Mossad is engaged in an espionage activity not only in Iran, but also in neighboring countries through Ron Arad Foundation's website.
If the country's citizens, cooperating with the Foundation, surrender with confessing the guilt, then leniency will be shown towards them, Moslehi said.
Moslehi didn't say the number of arrested peoples.
In early January, Iran exposed a ring of the Israeli spies responsible for nuclear scientist Masud Ali Mohammadi's assassination, the Iranian National Security Ministry said earlier.
