The problem as I see it with those images is the rubble has been cleaned up a bit which takes away some of the information that would have been available as to blast direction, power etc.
I haven't had time to look closely but has anyone had time to work out the centre of the blast - if it was located in the photo and not off to one side.
Edit
My quick guesstimate is that the centre of the blast, based on angle of damage was the Square, dark blue roofed building, top left of the compound. Also based on the fact that not much left of it, however as the debris has been cleaned up a bit this may be misguided.
I also can't see any hole in the ground, which even a ground detonated explosion should have left some sort of crater. Would love to see a more detailed satellite photo.
Anyone else care to comment ?
