I was recalling the port explosion as well - and that was attributed to the munitions stored there ... I guess this means Hezbollah had a missile store alongside the HQ (that would make sense)
Still trying to figger out all the red color myself. Never seen that much and brightness before. Your thot that it might be building materials is worth a look. It wouldn’t be ANFO unless it had something weird added to it. I use ANFO and , by itself, it will just blow white or light gray.
I usually can guess what blew in an explosion from either the charge or the secondary but this one is weird. Stored rocket motor fuel, maybe with some iron content, might be involved. No telling what kind of brew the muzzards are mixing up/
An early thot was maybe it was muzzie blood but even Noseroller’s nose couldn’t bleed that much? Did they ever rebuild that Beirut granary?
