In his annual report to the UN Security Council on conflict-related sexual violence, Guterres said that Israel and Russia could be listed next year among the parties “credibly suspected of committing or being responsible for patterns of rape or other forms of sexual violence”.

In his warning to Israel, Guterres said he was “gravely concerned about credible information of violations by Israeli armed and security forces” against Palestinians in several prisons, a detention centre and a military base.

“Cases documented by the United Nations indicate patterns of sexual violence such as genital violence, prolonged forced nudity and repeated strip searches conducted in an abusive and degrading manner,” Guterres wrote.

In the case of Russia, Guterres wrote that he was “gravely concerned about credible information of violations by Russian armed and security forces and affiliated armed groups”, primarily against Ukrainian prisoners of war, in 50 official and 22 unofficial detention facilities in Ukraine and Russia.
