Hezbollah launch attack on Israeli troops

[Stannis Baratheon]

If it is a U.N. building, then U.N. can no longer claim that they are a neutral, so it does not matter.
Once it can be determined that protected zones are used by Hamas for military purposes,
it OBVIOUSLY voids any agreement.
Still there will be a political price to pay.

That's not how it works. If it was from a building that is operational then UN would have been considered not neutral. UN has been a neutral agency throughout the conflict and Israel killing aid workers isn't a new thing.

Hamas Strategy is to protect their assets by violating the Geneva Convention.
Using Hospitals for headquarters, transporting soldiers in ambulances,
boobytrapping "civilian" buildings and use them as starting points for tunnels,
makes civilian buildings, hospitals and ambulances military targets.

Israel plans on turning Gaza into a concentration camp and intimidate aid workers and international human rights agencies from going to Gaza so that they don't witness Israel's warcrimes and can't help Palestinians during the genocide.
