Nine employees of the UN agency for Palestinian refugees, UNWRA, may have been involved in the Hamas-led attack on Israel on October 7, according to the United Nations.
All nine were dismissed, said Farhan Haq, deputy UN spokesman.
He said the UN had completed an investigation into allegations by Israel about the involvement of UNWRA staff.
The unprecedented attack last fall killed about 1,200 people and took 251 others back to Gaza as hostages.
Mr Haq did not specify what the precise involvement of the staff members would have been.
“For us, any participation in the attacks is a huge betrayal of the kind of work we should be doing on behalf of the Palestinian people,” he said.
The UN investigated a total of 19 members of UNWRA staff, after Israel claimed 12 took part in the attack.
Israel later claimed that more than 450 UNWRA staff were members of terrorist organizations, but a UN investigation published in April found that Israel had provided no evidence for these claims.
UNRWA, which employs 13,000 people in Gaza, reported in March that some of its workers reported being pressured by Israeli authorities to make false statements while in detention.
Most countries withdrew their funding for the UN agency over the Israeli allegations.
In July, the UK joined other countries that had since resumed funding, leaving the US, UNRWA’s largest donor, as the only country not to have resumed donations.
