UN staff accusations

*UN staff in West Bank accuse Israeli authorities of campaign of harassment.

Documents seen by the Guardian list hundreds of incidents, including UNRWA workers allegedly being blindfolded and beaten.*

I see no reason to doubt these accusations. Those employees are Palestinians. It is quite common for the Israeli soldiers and border patrol, or the fanatical "settlers", to treat Palestinians brutally.

Why would they make an exception for those who work for UNRWA?
