The UN Relief and Works Agency (UNRWA) is shocked to find 20 rockets in one of their schools in Gaza:

The UN agency for Palestinian refugees is investigating the discovery of 20 rockets hidden in one of its vacant schools in the Gaza Strip. The UNRWA condemned the incident as a “flagrant violation” of international law, adding that the rockets had been removed and that the relevant parties had been informed.

Israel regularly accuses Hamas and other militant groups in Gaza of using civilian installations to store and rockets, including during the current conflict, which began on 8 July.

I find the protestations of UNRWA to ring hollow.

While I understand that the agency needs to maintain good a relationship with the authorities in Gaza in order to effectively provide services, this sort of behavior has been the rule, not the exception, with UNRWA for nearly 70 years.
