Three Hamas militants wounded in Gaza in a Gaza explosion, and not only does Israel deny involvement, but Hamas agrees that the IDF had nothing to do with it.

It could be Islamic Jihad, of course, but given the PLO’s record on both conventional and urban fighting, their military record implies that they are over matched by a mean little kid with a pea shooter, this seems more the work of the PLO, particularly Fatah.

It requires a significant investment in resources and planning, but very little risk to the perps.
