Iranian air defenses fired a missile as part of an exercise on Saturday over the central town of Natanz, which houses nuclear installations, state TV reported, after local residents reported hearing a large blast.
The TV said air defense units fired the missile to test a rapid reaction force over Natanz.
“Such exercises are carried out in a completely secure environment … and there is no cause for concern,” Army spokesman Shahin Taqikhani told the TV.
