June 21 (UPI) -- The U.S. Federal Aviation Administration issued an emergency order prohibiting U.S.-registered aircraft operators from flying over the Persian Gulf and the Gulf of Oman due to increased tensions with Iran.
"The [Notice to Airmen] warns pilots that flights are not permitted in the overwater area of the Tehran Flight Information Region until further notice, due to heightened military activities and increased political tensions that might place commercial flights at risk," the FAA said in a statement Thursday. "The NOTAM applies to all U.S. air carriers and commercial operators."
Several airlines have announced that they will also be avoiding Iranian airspace, including British Airways, Qantas, Lufthansa, Singapore Airlines and KLM.
