The Palestinian President’s spokesperson has called the United States’ withdrawal of UN relief funding a "flagrant assault against the Palestinian people".

UN Spokesperson Chris Gunness said the impact of the funding cut would be widespread, causing some of the most marginalised Middle Eastern communities to suffer.

The US was previously the largest donor to the United Nations Relief and Works Agency, but now believes the organisation is "irredeemably flawed".

The UNRWA supports over 5 million Palestinian refugees with health care, education and social services.
