U.N. experts say in a report that they have “reasonable grounds to believe” some victims of Hamas’s Oct. 7 attack on Israel were raped and sexually assaulted, and that some of the hostages taken into Gaza have been subjected to sexual violence and torture that “may be ongoing.” In northern Gaza, visits by the World Health Organization to two hospitals over the weekend revealed a severe lack of food and aid that had resulted in the deaths of 10 children, the agency said, though local health officials have reported a greater toll.
