🇮🇷 - Rerum Novarum have geolocated the footage to: 27.12474, 56.06764.

See photo 1: We have marked the point of the initial fume on the map as a red flame. The point from which the footage was captured has also been marked as a purple X, the arrow indicates the direction of recording.

The vital detail of the footage are the two trucks up front, the trucks can be seen carrying 'sandbags', packaging identical nitrogen tetroxide, N₂O₄, a powerful oxidant. If near combustible material (the initial fume), it will explode, and explode very powerfully.

The question is, why were two truck loads of N₂O₄ being moved in the direction of the fume? And then parked in front of a warehouse. The compounds were just delivered to the doorstep of the already existing fire, and then left there to explode...

See photo 2: Rerum Novarum have identified the warehouse on the right-hand side of the trucks belongs to Sinai Maritime and Port Services. According to Financial Times, the company is in no way involved in storing ballistic or rocket fuels.

However, it is likely they were making their way towards a large storage facility further west (marked with a green flag, with the route shown on map). There is no information for this warehouse, which is normal for Iran when storing sensitive materials.

But it doesn't explain why the trucks were parked, or this route was even taken, as the warehouse in the west has its own access road. Negligence?
