The U.S.-based social media platform X has removed blue verification badges from several senior Iranian officials’ accounts following allegations that it provided paid services to individuals under U.S. sanctions. The action came after a report by the Tech Transparency Project claimed that X’s paid subscription service, X Premium, was available to sanctioned Iranian figures.

Among those whose verification was revoked are Iran’s Foreign Minister Abbas Araghchi, Judiciary Chief Gholamhossein Mohseni Ejei, and Supreme National Security Council Secretary Ali Larijani. Under U.S. sanctions law, American companies are prohibited from conducting business with certain individuals and entities. X has not issued any official comment on the matter.

The platform, owned by Elon Musk, had previously faced criticism for altering the design of the Iranian flag emoji on its web platform during protests in Iran, replacing the Islamic Republic emblem with the older “lion and sun” symbol associated with monarchist groups.
