Israel’s mission to the United Nations says it will have no contact with UN Secretary-General António Guterres’ office while he remains in the role. The decision follows Israel’s complaint that Guterres is associated with a sexual violence blacklist that includes Israeli personnel, an issue raised through UN engagement connected to allegations involving Palestinian detainees. According to reporting, Israel’s UN ambassador shares that Guterres told Israel there is an “increasing number of cases” of sexual violence involving Palestinian detainees, as reflected in a letter communicated between them. The Israeli mission frames its move as a suspension of contact with the UN chief’s office, while UN officials and other parties are not described in the provided accounts beyond the secretary-general’s communication about alleged incidents. The dispute centers on the question of how Israel and the UN address allegations of sexual violence and related reporting mechanisms, and the consequences for diplomatic engagement within the UN system.
