The U.N. General Assembly is voting Thursday on a U.S.-initiated resolution to suspend Russia from the world organization’s leading human rights body over allegations that Russian soldiers killed civilians while retreating from the region around Ukraine’s capital.

U.S. Ambassador Linda Thomas-Greenfield made the call for Russia to be stripped of its seat on the 47-member Human Rights Council in the wake of videos and photos of streets in the town of Bucha strewn with corpses of what appeared to be civilians. The deaths have sparked global revulsion and calls for tougher sanctions on Russia, which has vehemently denied its troops were responsible.

“We believe that the members of the Russian forces committed war crimes in Ukraine, and we believe that Russia needs to be held accountable,” Thomas-Greenfield said Monday. “Russia’s participation in the Human Rights Council is a farce.”

General Assembly spokeswoman Paulina Kubiak said the assembly’s emergency special session on Ukraine would resume Thursday morning when the resolution “to suspend the rights of membership in the Human Rights Council of the Russian Federation” will be put to a vote.
