What happened
During a flight proceeding from Chiraz toward Tehran, an aircraft encountered severe weather conditions characterized by heavy storms. While the plane was in its cruise phase of flight, an explosion occurred onboard. Following this event, the aircraft descended and crashed in the vicinity of Zarand.
There were 23 fatalities recorded as a result of the accident, with no survivors reported among the occupants.
Findings
Official investigations into the destruction of the aircraft suggest that the incident was triggered by an atmospheric event. The primary factor identified is that the airplane was struck by lightning during its flight through the storm, which led to the subsequent explosion and loss of control.
