The United States and Israel have officially quit the United Nations Educational, Scientific and Cultural Organization (UNESCO) at the stroke of midnight on New Year's Day, the culmination of a process triggered more than a year ago.
The withdrawal is mainly procedural yet serves a new blow to UNESCO, co-founded by the US after World War II to foster peace.
The US has demanded "fundamental reform" in the agency.
UNESCO is best known for its work to preserve heritage, including maintaining a list of World Heritage sites, and programmes to promote education in developing countries.
The withdrawals will not greatly affect UNESCO financially, since it has been dealing with a funding slash ever since 2011 when both Israel and the US stopped paying dues after Palestine was voted in as a member state.
Since then officials estimate that the US – which accounted for around 22 percent of the total budget – has accrued $600m in unpaid dues, which was one of the reasons for President Donald Trump's decision to withdraw. Israel owes an estimated $10m. Al Jazeera.
