Israel has provided the Biden administration with a new dossier providing with information about how staffers for a United Nations agency assisted or supported the Hamas terror attacks on Oct. 7, Fox News has learned. 

The dossier specifically alleges that 12 employees who worked with the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) aided in different capacities. 

According to the dossier, one UN staffer joined Hamas terrorists in raiding an Israeli kibbutz and directly participated in violence, another staffer kidnapped an Israeli woman, holding her hostage in their personal home, and a third UN staffer doled out ammunition to the Hamas terrorists.
