What body? A suicide vest does a lot of damage, I doubt the Delta Forces spent time vacuuming up the bits and pieces.
I think that most of the suicide vest bombers kinda implode the Torso and the Arms, Legs and Head go up and out. Having never Witnessed one Im just speculating.
I doubt that Delta Team took much time cleaning up whimpering terrorscum boys peices/parts. The bodies of him and 3 children after Boom 💥 plus the Cave debris falling on top of them was probably close enough to burial and would be a waste of time to do much more besides maybe setting a few Charges to finish sealing off that end of the dead end (no Pun intened) cave.
