The Iranian military began a five-day nationwide military drill dubbed "Defenders of the Sky" on Tuesday, state-run IRNA reported.
"Army Defense Forces, Islamic Revolutionary Guard Corps (IRGC), police and Basij have joined the military exercise," drill spokesman Brig.-Gen. Hamid Arjangi told IRNA.
"The military maneuver is staged across the country unlike last year's," he said.
"Aircrafts of the enemy dubbed 'Orange Forces' were identified and intercepted by our radar systems and then the order to confront the enemy was given."
He added, low-, mid- and high-altitude missiles were being used in the drill.
