This report in The Times of London says 2700 tons of exploding ammonium nitrate was stored in one of the warehouses at Beirut port. This caused the explosion. Yet no one knows what caused the explosion and what caused the accident. It says in Beirut no one is in control of safety and security because the government is run by many parties and factions.

The strange story of an aging ship in extremely bad shape from a Black sea port in Georgia with a 2750 ton shipment of ammonium nitrate with a crew on unpaid wages making its way to port Beira in Mozambique in 2013. It is leased by a Russian owner living in Cyprus who would make $1 million for transporting the shipment to Fabrica de Explosivos de Mozambique. It makes an unscheduled stop in Beirut after problems with seamen on the crew to pickup some heavy machinery which might help pay the ship's crews wages. The machinery does not fit and in any case the ship is in such bad condition and cannot handle any machinery.  The port authorites are interested only in the docking fees which the indebted Russian owner does not pay and abandons his leased ship. The port of Beirut impounds the ship for unpaid docking fees which turns out to be the reason the ship remains in Beirut harbor. The ship fails shipping standards and takes in water, it remains in Beirut harbor till 2014 when the ship sinks. Before that the Beirut authorites for some strange reason unload the ammonium nitrate and leave it in Hangar 12 warehouse where it remained till it exploded yesterday. The authorites never gave much thought to the ammonium nitrate and its dangers till after unloading it. After unloading no one accepted responsibility. The Russian who had leased the ship was living in Cyprus and took no responsibility. The government of Lebanon also did not know what to do with it.  Repeated attempts by the port authorites asking the government to take some action for disposal fails to lead to any action. There is now a sense that Lebanon is a failing state because of the nature of this incident.   ...

The strange story of port authorites behaviour in Beirut for an incoming ship from Georgia on the Black Sea loaded with ammonium nitrate explosive materials- keeping the ship in port because it lacked the proper papers and because it was not fit to sail. If allowed to leave the ship would probably not caused an explosion in a congested port area. The mystery of the behaviour of port authorites extends to the next step where the port authorites actually unloaded the ship's explosives material to a port hangar warehousing area when there was no need to do so or no need to keep the ship in Beirut. waters as its actual destination was in Mozambique in the west coast of Africa.
