According to Reuters, Israel coerced and tortured UNRWA workers, subjecting them to "severe physical beatings, waterboarding", to force false confessions about association with Hamas and participation in the Oct 7th attacks.
Israel would later accuse UNRWA of being staffed by Hamas terrorists and participating in attacks against civilian Jews, calling for suspension of funding and blocking UNRWA aid from reaching Gaza civilians.
This resulted in massive starvation of Palestinian civilians and widespread malnutrition among their children.
Most countries which had suspended funding to UNRWA have resumed it, after Israeli claims have not been substantiated, with the notable exception of the US.

I figured that was a more useful description than "jew" or "zionist" because not all of them are jews, nor are all of them even zionists (it's pretty clear to me right now that there's an anti-zionist cabal, comprised partly of jews, with some fairly significant control over the levers of power.) So I'm not using euphemism there, I'm simply describing them with their worst sins.
