Some US media outlets say vehicles and facilities belonging to a UN aid agency operating in Gaza may have been used during Hamas's October 7 attack on Israel.

The UN Relief and Works Agency for Palestine Refugees in the Near East, or UNRWA, has opened an investigation into allegations that some of its staff members were involved in the deadly attack. The agency is acting on information provided by Israel.

The US news site Axios quoted a senior Israeli official as saying the information indicates UNRWA staffers actively participated in the attack, and the agency's vehicles and facilities were used.

The official told Axios that a lot of the intelligence was obtained during interrogations of Hamas militants who had been arrested.

Following the allegations, the United States, the largest UNRWA donor, and five other countries, including the UK and Canada, announced that they will pause additional funding for the agency until necessary measures have been taken.

Israeli forces are continuing their attacks on the southern city of Khan Younis and elsewhere in the Palestinian enclave. Health authorities in Gaza said on Saturday that 174 people had died in the previous 24 hours. They said that brought the overall death toll to 26,257.

UNRWA plays a pivotal role in distributing aid supplies and running shelters in Gaza. Concerns are growing that the latest developments could make the humanitarian situation there worse.
