Iran temporarily closed its airspace to commercial flights without explicit explanation on January 14-15, 2026, amidst widespread civil unrest and heightened tensions with the United States. This move comes as Iran's foreign minister denied plans to execute protestors, while the Islamic Republic warned against US or Israeli intervention in its domestic affairs, threatening a 'decisive response' to any 'strategic mistake'. Donald Trump, though no longer US President, has been actively commenting on the situation, threatening US intervention if Iranian security forces use deadly force against peaceful protestors. He stated the US was 'locked and loaded' and ready to 'come to their rescue' if protestors were harmed, leading to a strong diplomatic backlash from Iran at the UN Security Council. The sudden airspace closure significantly impacted international aviation, particularly affecting flights utilizing key East-West routes over Iran. Major Indian carriers, Air India and IndiGo, promptly issued advisories, confirming that several of their international flights were either rerouted or canceled for passenger safety. IndiGo acknowledged the situation as a 'sudden airspace closure' beyond its control, advising passengers of potential delays and offering rebooking or refund options. Air India also confirmed using alternative routes, leading to longer flight times and some cancellations. The safety concerns are amplified by past incidents, such as Iran's accidental shootdown of Ukraine International Airlines Flight PS752 in January 2020 during a period of similar US-Iran military tensions. The ongoing developments underscore the volatile geopolitical climate in the Middle East and its immediate implications for global air travel.
