I’ve never seen any kind of reports that say - either - that Iran is paying the UN to house and hide weapons and armaments, or, that the UN is doing that for free ... LOL ...
Please do give me a report on the United Nations doing that ... I would find it enlightening.
This particular report of weapons being found in a UN facility appears to be something they don’t want there, which is why it was reported. But, if you’ve got something where they’re actively helping Hamas by doing that, it would definitely be very enlightening!
Don’t know about Iran.
About the UNRWA, google ‘al fakhoora school incident’.
