Ammonium nitrate alone wouldn’t do that, and its deflagration (burning) would have produced ash-colored smoke. The smoke plume from Beirut was reddish brown like you’d see from a High Melting Explosive (HMX) like Octogen, a high-grade rocket fuel of which ammonium nitrate is one of four ingredients (along with hexamine, nitric acid and acetic acid). More likely what blew yesterday was an Iranian ammunition warehouse, or even an Iranian HMX production facility. Where do we think all those rockets fired against Israel come from, or what fuels them? Imminent war delayed.

This.

Highly probable, if you watch the explosion in slow-mo you will see the brissiveness of the explosion. It also seems to me that the main explosion seems to have come from under ground. This was not an AN explosion.
