According to sources, what the Islamic Republic is reporting to be a chemical facility that faced a major explosion on Sunday is actually a key location for the production of unmanned aerial vehicles (UAV).

Isfahan, which is located nearly five hours south of Tehran, faced a significant explosion on Sunday at a factory suggested by many to be used to produce UAVs. The incident occurred at Sepahan Nargostar Chemical Industries around 4:00 AM and resulted in nine people being injured.

Despite claims that the site is set apart for manufacturing “industrial-commercial explosive materials”, several sources claim that the facility is used for producing drones, making it a military target.

The explosion came within three days of Israel shooting down an Iranian drone near its border with Jordan as the conflict between Gaza (Hamas) and the Jewish state came to an end. An Iranian medical spokesman, Abbas Abedi, said, “The reason for the explosion at the Sepahan Nargostar chemical industry is under investigation while nine injured people have been transferred to hospital.”

Upon the explosion, residents of the region reported shaking homes, trying to determine if something large had crashed or an earthquake had taken place.
