More than a dozen employees of the U.N. agency for Palestinian refugees are believed to have played a role in Hamas-led attacks on Israeli cities on Oct.

7. This is according to an intelligence dossier compiled by the Israeli government and seen by The Washington Post on Monday. The United Nations is now examining the allegation. The agency fired nine employees after the dossier was published. The allegations of complicity have plunged the United Nations into crisis and jeopardized its operations in the Gaza Strip. The UN is the main provider of aid and shelter in the besieged enclave, and has warned that funds could be exhausted by the end of February.
