The advisor to Iran's supreme leader strongly criticized the suspension of flights by neighboring countries such as Iraq, Oman, and the UAE, which joined the US sanctions against Iran. He warned that 'intra-regional flights' would not be free for anyone, implying retaliatory measures. He suggested that if Iran's airspace is blocked, it could block passage through its airspace in the Middle East region, including the Strait of Hormuz. This comes as neighboring countries have imposed a complete ban on Iranian airlines due to intense sanctions pressure from the US Treasury Department. As many countries, including Iraq, Oman, and the UAE, are controlling the entry of Iranian flights, there are concerns about disruptions to global air passenger and cargo transportation passing through the Middle East region in the future.
