According to Iran’s official IRNA news agency, the country’s air force is holding its annual military exercises aimed at defending Iranian air space.

Drills are taking place near the central city of Isfahan, where Iran’s key nuclear facilities are located.

Facilities located there include the Natanz uranium enrichment plant. The air base there was key in the Iran-Iraq war.

The military spokesman for the two-day drill, Gen. Masoud Rouzkhosh, says it aims to improve and update capabilities of the air force, as well as display Iran’s military power.

He says fighter jets, bombers and drones will be tested during the drill near Isfahan, about some 400 kilometers, or 250 miles, south of the capital, Tehran.
