• UAE suspends all flights from Iranian airlines in response to US sanctions.
• Four Iraqi airports halt flights to and from Iran, citing US sanctions enforcement.
• Iranian officials threaten airspace disruption in retaliation for flight bans.
• Secondary sanctions target international firms servicing Iranian carriers.
• Iran faces intensified isolation in the aviation sector amid deepening economic crises.

The United Arab Emirates has halted flights operated by Iranian airlines, following the implementation of new sweeping US sanctions aimed at crippling Iran’s aviation sector. This suspension was announced by the UAE's General Civil Aviation Authority, which indicated that the decision was made based on the sanctions imposed by the US, thereby preventing Iranian airlines from utilizing airports worldwide, according to Al Jazeera and India Times.

Concurrently, four Iraqi airports—including Baghdad, Najaf, Erbil, and Sulaimaniyah—have also suspended all flights to and from Iran, a measure that aligns with the US policy to restrict Iranian access to international air travel. This move reportedly followed directive from Iraq’s government, with Najaf airport citing safety and compliance concerns, according to Al Jazeera and India Times.

Iran has responded to these aviation restrictions with threats of retaliation, suggesting that it could retaliate by disrupting air traffic for countries that comply with US mandates. A senior advisor to the Iranian leadership warned that "no one in the region can either" if Iran is denied airport services, indicating a readiness to escalate tensions in the region, according to Channel News Asia and India Times.

The tightening of sanctions reflects a broader strategic shift from the US to implement "secondary sanctions" aimed at international companies that do business with Iranian aviation entities. The US Treasury has warned that any airport facilitating Iranian carriers could be excluded from the US dollar financial system, placing additional pressure on aviation networks globally, as noted by Channel News Asia and Al Jazeera.

The ongoing sanctions are anticipated to deepen Iran's economic woes, already strained by previous US restrictions, with significant repercussions for its aviation sector, which has seen dwindling operational capacity. Iranian carriers remain reliant on limited routes to destinations such as Turkiye and China, as they attempt to navigate the intensified isolation imposed by these sanctions, according to Al Jazeera and Channel News Asia.
