(Snip)An exiled Iranian dissident group, the Mujahedin-e Khalq or MEK, meanwhile claimed that the blast hit a missile base run by the Revolutionary guard rather than an ammunition depot.

Former MEK spokesman Alireza Jafarzadeh, citing what he called reliable sources inside Iran, said that the explosion hit the Modarres Garrison of the Islamic Revolutionary Guard Corps west of Tehran.

According to this article in Persian the number of dead are 170 - 300 and the cause of the incident is either exploding missile fuel or caused by a test of explosives or ammo.

My guess is that it was caused by a error in a missile test. The general would not have been there if it was a simple transport of ammo. If my guess is correct then a lot of other key persons in the Iranian missile program are as well dead or wounded.

That’s MEK trying to make themselves look good by ‘revealing’ what was fairly common knowledge.
