Accounts from someone on the firing line was it was a shoulder fired HE round that "Dolphined" after it left the tube and went astray. NOT artillery. This round hit a gas well which exploded and flattened the 3 Kill Houses that were full of troops which happened to be in close proximity of the well. Approx 300 troops inside and many waiting outside them. There is nothing but splinters left of them. This also started a major fire that was fed by high winds that swept through the main Bivouac site housing the majority of troops in the field. The amount of injured is staggering and the fatality count IS going to climb as they recover more victims. In my 20+ years in the Army, I have only heard of a dolphining round happening once from a shoulder fired rocket. Not sure what would cause this other than possibly a faulty propellent.
