I don't get one thing though. Something seems to be burning really hot in that video but it also seems to cover a wide area.
So, Babak says they have hit places like Havanirouz, ammo and fuel storage facilities. That can explain the secondary explosions and the continuous burning in the video, particularly Havanirouz seems like a reasonable choice for that particular video, but who uses bunker busters to hit these places? Since when they're deeply hidden underground facilities?
If we assume that they have hit a missile city or something built under the ground, it will explain secondary explosions, but shouldn't the flame look like a column of fire coming out of multiple locations like entrances/exits, etc.?
