There are UN inspectors based in GAZA.
In an interview with CNN a UN inspector in GAZA said " The local authorities did not give me free access to the area or were very unhappy that I was trying to investigate something that had clearly gone wrong from their point of view.”
Marc Garlasco, the former defense intelligence analyst and UN war crimes investigator, says there are signs of a lack of evidence at the Al-Ahli Hospital site.
He was allowed in but had a "guided tour" the day after.
He then went on to say “When I investigate a site of a potential war crime the first thing I do is locate and identify parts of the weapon. The weapon tells you who did it and how. I’ve never seen such a lack of physical evidence for a weapon at a site. Ever. There’s always a piece of a bomb after the fact. In 20 years of investigating war crimes this is the first time I haven’t seen any weapon remnants. And I’ve worked three wars in Gaza.”
