Secondary Sanctions Target Foreign Entities Servicing Iranian Carriers
The US is set to impose secondary sanctions on September 23, 2026, targeting foreign entities that service Iranian carriers, effectively shutting Iranian commercial airlines out of international airspace. The measures, announced by US Treasury Secretary Scott Bessent, could affect airlines including Iran Air, Mahan Air, and Qeshm Air. The warning means service providers could risk sanctions if they refuel Iranian aircraft, provide landing or airport services, or sell tickets for Iranian carriers. The announcement represents an escalation of Washington’s broader economic pressure campaign against Tehran, as reported by Unknown Source.
