One example:
The cargo had been stored at the port since it was confiscated from a ship years earlier. Based on the timeline and the size of the cargo, that ship could be the MV Rhosus. The ship was initially seized in Beirut in 2013 when it entered the port due to technical problems, according to lawyers involved in the case. It came from the nation of Georgia, and had been bound for Mozambique...
The stockpile is believed to have detonated after a fire broke out nearby in what appeared to be a warehouse holding fireworks. Daher, the customs official, said he did not know if there were fireworks near the site.
Another theory is that the fire began when welders were trying to repair a broken gate and a hole in the wall of Hangar 12, where the explosive material was stored..
So.. Not ‘fireworks’ after all
I did not think stored ammonium nitrate would burn and detonate like that unless mixed with an accelerant.
