DEIR AL-BALAH, Gaza Strip (AP) The U.N. agency for Palestinian refugees fired a number of its staffers in Gaza suspected of taking part in the Oct. 7 attack by Hamas and other militants on southern Israel, its director said Friday, prompting the United States the agencys biggest donor to temporarily halt its funding.

The agency, known by its acronym UNRWA, has been the main agency providing aid for Gazas population amid the humanitarian disaster caused by Israels offensive against Hamas in Gaza triggered by the Oct. 7 attack. UNRWA officials did not comment on the impact that the U.S. halt in funding would have on its operations.

UNRWA chief Philippe Lazzarini said it terminated contracts with several employees and ordered an investigation after Israel provided information alleging they played a role in the attack. The U.S. State Department said there were allegations against 12 employees. UNRWA has 13,000 staffers in Gaza, almost all of them Palestinians, ranging from teachers in schools that the agency runs to doctors, medical staff and aid workers.

In a statement, Lazzarini called the allegations shocking and said any employee involved in acts of terror will be held accountable, including through criminal prosecution.

He did not elaborate on what the staffers alleged role was in the attacks. In the unprecedented surprise attack , Hamas fighters broke through the security fence surrounding Gaza and stormed nearby Israeli communities, killing around 1,200 people, mostly civilians, and kidnapping some 250. Other militants joined the rampage.

UNRWA reiterates its condemnation in the strongest possible terms of the abhorrent attacks of 7 October and calls for the immediate and unconditional release of all Israeli hostages, Lazzarini said.
