The probable involvement of certain UNRWA employees in the attack has been scrutinized since January, when Israel accused the primary assistance organization in war-torn Gaza.
The UN’s Office of Internal Oversight Services stated it uncovered enough evidence to suggest nine personnel were involved in the 7 October massacre, in which Hamas militants entered southern Israel and killed 1,200 people while holding 250 others prisoner.
To reach their judgment, the investigators studied internal UNRWA material such as staff records, email, and other communication data.
The UN monitor said it also relied on evidence provided by Israeli officials, but because it did not have direct access to it, the organization was unable to independently verify the claims.
UNRWA has been the primary body giving aid to Palestinians in Gaza during the 10-month conflict, which Gaza health officials claim has killed more than 39,600 people and resulted in a massive humanitarian crisis.
UNRWA, which denies cooperation with Hamas, claims more than 200 of its employees have been killed.
