Senior defense officials told Barbara Starr on November 17th that the U.S. believes the Iranians were mixing volatile fuel for a rocket motor for a large ballistic missile when the accident occurred. The explosion took place inside a base called Bid Ganeh, west of Tehran, which is reportedly used to manufacture and store Iran’s long-range ballistic missiles.
At least 17 people, including a general, died as a result of an explosion on the military base near Tehran, Iranian state media reported at the time of the explosion.
This site 40 km (25 miles) away from Tehran, was described at the time by the Revolutionary Guards as an accident, while one local member of parliament said an ammunition depot had exploded.
One of those killed was Gen Hassan Tehrani Moghaddam, who was said to have been working on Iran’s missile program.
The force of the explosion was so great that it shook windows in many surrounding towns, according to Iranian news sites and witnesses quoted at the time
