💥🇬🇧 Rettendon, Essex, UK explosion:

The prevailing theory is that this was the result of fertiliser being stored in the warehouse igniting and then exploding. Basically a massive fertiliser bomb.

Looking closer inside the warehouse on Streetview, you can see a lot of large sacks stored inside.

But still, if this was an accident, there are going to be serious questions asked here as it seems safety protocols haven't been adhered to.
