Iranian airspace is officially closed. Reports of fighter jets heard over Eastern Iraq.

“All the signals are that a US attack is imminent, but that is also how this administration behaves to keep everyone on their toes,” a Western military official said.

Iran temporarily closed its airspace early on Thursday morning, issuing a NOTAM (Notice to Airmen) to all flights except international ones to and from Iran with official permission, as Western military officials say US military action in the country is “imminent.”

Flight tracker websites showed the airspace over Iran and Iraq emptying rapidly prior to the NOTAM’s issuing. The prohibition lasted more than two hours and ended at around 2:30 a.m. Israel time.
