The UN Independent International Commission of Inquiry on the Occupied Palestinian Territory, including East Jerusalem determined that it is a genocide in a report released September 16: https://www.ohchr.org/en/press-releases/2025/09/israel-has-c...

The UN Independent International Commission of Inquiry (COI) is not a legal body, which would be the sort of body that is able to make a genocide determination. It also does not speak on behalf of the UN, given that it an independent commission of inquiry.

I am curious to see what the ICJ ruling in South Africa's case will be. That would be an actual legal body charged with making a genocide determination.
