Iran Shuts Down Airspace Amid Rising U.S. Tensions; Foreign Officials Warn Against Travel to Israel

15 January 2026 World

TEHRAN, Iran — In a dramatic escalation of regional tensions, Iran issued a Notice to Airmen (NOTAM) late Wednesday, effectively closing its airspace to nearly all flights except international flights granted prior permission. The closure, which lasted just over two hours, disrupted numerous commercial and cargo flights, forcing rerouting and denials of entry as tracked by Flight Radar 24 data. This move comes amid mounting friction between Tehran and Washington, with the U.S. military reportedly warning of a potential imminent attack in the region.

The Iranian government’s decision to limit air traffic coincides with heightened unrest within the country, where widespread protests have drawn international condemnation. While former President Donald Trump claimed that the Iranian government’s deadly crackdown on protesters has ceased, military officials have cautioned that the situation remains volatile and could escalate rapidly.

Following the airspace closure, U.S. embassies in Jerusalem, Qatar, and Kuwait issued security alerts urging increased caution. The advisories included restrictions on non-essential travel to key military installations such as Al Udeid Air Base in Qatar and Camp Arifjan in Kuwait, temporarily halting movement into these facilities. Similarly, the United Kingdom’s Foreign, Commonwealth & Development Office (FCDO) issued a travel advisory recommending against all but essential travel to Israel, citing a “heightened risk of regional tension” that could disrupt travel and other activities.

The U.S. Department of State has not publicly detailed the specific nature of the military warnings but has confirmed ongoing assessments of the security environment in the Middle East. The heightened alert status reflects concerns over potential Iranian retaliation or escalation in response to U.S. actions and regional dynamics.

Iran’s Supreme Leader, Ayatollah Ali Khamenei, has remained a central figure in the country’s response to both internal dissent and external pressures. Despite the internet blackout imposed during the protests, some Iranians have managed limited international communications, underscoring the complex information landscape amid the unrest.

The closure of Iranian airspace and the subsequent travel warnings come at a time when the international community is closely monitoring the situation. The U.S. Department of State continues to advise American citizens to exercise caution in the region, while allied governments have echoed similar concerns. The security measures reflect a broader pattern of heightened military readiness and diplomatic caution as tensions between Iran and the West remain fraught.

This development also follows reports of the U.S. withdrawing some military personnel from Middle East bases, a move officials describe as precautionary amid the threats. The Department of Defense has not confirmed specific troop movements but emphasizes the importance of maintaining regional stability.

As Iran’s airspace closure temporarily disrupted international travel routes, airlines and governments remain vigilant for further developments. The situation underscores the fragile state of affairs in the Middle East, where geopolitical rivalries and domestic unrest intertwine, posing challenges for global security and diplomacy.

For travelers and businesses, the evolving advisories from the UK Foreign Office and U.S. agencies highlight the need for caution and preparedness amid the unpredictable security environment. Analysts warn that any further escalation could have widespread implications for international air travel, trade, and diplomatic relations in the region.
