A quick heads up that the video above contains some bad language, although you can’t really blame those filming because what they are witnessing is pretty unreal.

Also stick around and watch to the end, the final blast is the biggest of the lot.

For a point of comparison check out the video we brought you yesterday, filmed from further away but still showing just what happens when a reported 21 tonnes of TNT goes up in flames.

The death toll from the explosion has now risen to above 50, with those injured numbering more than 500.
