Iranians living abroad could have property confiscated and face other legal penalties if ​they express support for the United States and ‌Israel, the Iranian prosecutor general’s office said on Monday.

Some members of the Iranian diaspora who want political change ​in Tehran took to the streets of ​European and American cities to celebrate the ⁠killing of Supreme Leader Ayatollah Ali Khamenei ​in the US-Israeli war against Iran.

Iran on Monday named ​Mojtaba Khamenei to succeed his father.

“A warning has been issued to those Iranians living abroad who in different ways ​sympathise, support or cooperate with the American-Zionist (Israeli) ​enemy,” the prosecutor general’s office was quoted as saying by ‌state ⁠media.

“They will be met with the confiscation of all their properties and other legal penalties in accordance with the law.”

Newly established channels on Telegram ​have shared details ​of prominent ⁠Iranians living abroad who have posted comments critical of Iran’s clerical authorities ​and supportive of the US-Israeli military campaign ​that ⁠began on February 28.

Up to 5 million Iranians live abroad, the majority of them in the United ⁠States ​and Western Europe, according to ​Iranian government data.

Iranian media put their numbers closer to ​10 million.
