I read in the Daily Mail (My source for all US-based news, naturally), that the bomb was binary, and was not assembled when it went off. The only thing that detonated was the primary charge, and the much larger secondary charge did not go off.

From this photo it appears he was well strapped with secondary devices...

It’s obvious that only the primary charge went off not the bomb itself or he and the people around would be a bloody mess. Thank God whomever built it failed at bomb building .
