If there was any justice in this world UNRWA and it's parent agency the UN would be indicted for war crimes:

"Three IDF soldiers were killed on Wednesday in Gaza in an explosion at a booby-trapped UNRWA health clinic that housed the opening of a tunnel, the IDF's Gaza Division commander, Brig. Gen. Micky Edelstein, said.

The clinic had apparently been abandoned by its UN personnel. UNRWA did not immediately respond to a request for comment."
