Powerful explosions near nuclear facilities in Iran

"Frightening reports have emerged from Iran. Several powerful explosions have been reported in proximity to the Nuclear Technology Center in Isfahan. It's speculated that anti-aircraft artillery may have caught fire. At this moment, the exact cause remains uncertain. Military sources allege that there were ongoing military exercises in the vicinity.....one narrative postulates a drone attack to which the air defense system responded immediately......cites Iranian military sources as stating that explosions near the Nuclear Technology Center were due to defensive exercises. Intriguingly, local Iranian sources claim there were no scheduled exercises in that area." MS
