UAE closes and reopens airspace — ~2-hour precautionary shutdown, Day 18 overnight

The UAE General Civil Aviation Authority announced temporary closure of UAE airspace as an 'exceptional precautionary measure' in the overnight hours of Day 18, amid the most intense escalation exchange of the conflict. Dubai International Airport — the world's busiest international hub — suspended all flight operations. The closure came hours after a separate IRGC drone strike targeted a fuel storage tank near Dubai International on Day 17, and as Iran and Israel exchanged simultaneous missile strikes and airstrikes targeting Tehran, Beirut, Tel Aviv, and northern Israel. The UAE airspace closure marks a significant escalation in the Gulf aviation impact of the conflict. Dubai International handles over 90 million passengers annually. Its repeated disruptions — from the Day 17 fuel tank strike to this Day 18 full closure — signal that the conflict is now imposing direct operational costs on global aviation routing and Gulf commercial infrastructure.
