The US has pulled out of the United Nations Human Rights Council, calling it a “cesspool of political bias”.
The “hypocritical and self-serving” body “makes a mockery of human rights”, said US envoy to the UN Nikki Haley.
Formed in 2006, the Geneva-based council has been criticised for allowing countries with questionable human rights records to be members.
But activists said the US move could hurt efforts to monitor and address human rights abuses around the world.
Ms Haley announced her country’s intention to quit the council at a joint news conference with Secretary of State Mike Pompeo, who called the council “a poor defender of human rights”.
