The US has reiterated its call for Russia to be suspended from the UN Human Rights Council - saying Washington "has assessed" that war crimes have been committed in Ukraine.

Linda Thomas-Greenfield, the US ambassador to the UN, told the Security Council "Russia should not have a position of authority in a body whose very purpose is to promote respect for human rights".

She said Russian participation "hurts" the human rights council's credibility, following the "unprovoked war and the humanitarian crisis".

Turning to Ukrainian President Volodymyr Zelensky, following his address to the security council, Thomas-Greenfield said: "We stand with the people of Ukraine as you face down this brutal attack on your sovereignty, your democracy, and your freedom."
