Israel accused 12 members of the UNRWA staff of fighting for HAMAS or other terrorist groups. This is being used as an excuse to cut off the aid to the Palestinians. Israel kept the information secret for months until a time when it badly needed to distract public opinion from the war crimes court's judgment against Israel.

The UNRWA is a UN humanitarian aid agency, not intended as a police force or peace keepers. It has 13,000 or so staff in Gaza, 99% of whom are Palestinians from Gaza. If 12 of them were fighting for HAMAS, that amounts to 0.1% of the total staff. For a large organization in Gaza to have such a small fraction of HAMAS fighters is doing pretty well at avoiding them.
