According to a report by the American CBS network, on September 25 local time, Mohammad Mohabel, senior advisor to Iran's supreme leader, said in a post on social media that 'aligning ourselves with the United States in its hostile policies will always be remembered by the Iranian people. Our position on this issue is clear: either all flights in the region can fly freely, or no one can.'
He emphasized, "If Iran is unable to fly or obtain airport services, other countries in the region will also be unable to possess such a possibility."
US Treasury Secretary Steven Beldest said earlier this week that starting on the 23rd, sanctions will be implemented to prevent foreign airports from providing refueling, ticketing, and other services to Iranian airlines. He stated that companies that ignore these sanctions “will be kicked out of the dollar system”.
After that, multiple countries enforced sanctions on Iran's aviation company by closing their national airports in accordance with the U.S. embargoes.
