The large blast that I mentioned yesterday in the Shati camp in Gaza was just a big misunderstanding, according to Hamas.
It wasn't aimed at any Hamas leader or anything like that. Just that a youth, unaffiliated with any of the many militant groups in Gaza, decided to put together his own bomb and it exploded prematurely...but caused no damage or injuries.
Because any kid in Gaza can pick up some TNT and explode a bomb large enough to force entire blocks to be cordoned off, and yet not get hurt or cause any damage.
The original story mentioned that the Hamas police kept everyone - including reporters -away from the site.
A perfectly rational explanation!
