The threat was issued in a statement by the Office of the Prosecutor General, which said such cooperation, if deemed harmful to national security, could bring confiscation of all assets and other legal penalties.
The statement cited Article 1 of a law passed in October that increased penalties for espionage and cooperation with Israel and other countries deemed hostile to Iran’s national security and interests.
Under that law, operational or intelligence activities carried out on behalf of Israel, the United States or other “hostile” governments or groups can lead to the confiscation of all assets and the death penalty, the statement said.
The warning came after some members of the Iranian diaspora seeking change in Tehran gathered in cities across Europe and the United States to celebrate the killing of Supreme Leader Ali Khamenei in the US-Israeli war against Iran.
At the same time, newly created Telegram channels have published details about prominent Iranians abroad who criticized Iran’s clerical establishment and backed the US-Israeli airstrikes that began on February 28.
Between 5 million and 10 million Iranians are estimated to live abroad, mostly in the United States and Western Europe, according to Iranian official data and domestic media reports.
