UN demands investigation of “mass graves” at Gaza hospitals | BBC News

"The UN's human rights chief has said he is ""horrified"" by the destruction of Gaza's Nasser and al-Shifa hospitals and the reports of ""mass graves"" being found at the sites after Israeli raids. Volker Türk called for independent investigations into the deaths. Palestinian officials said they had exhumed 283 bodies at Nasser hospital, some with their hands tied. It is not clear how they died or when they were buried. Israel's military said claims that it buried bodies there were ""baseless"".But it did say that during a two-week operation at the hospital in the city of Khan Younis in February, troops ""examined"" bodies buried by Palestinians ""in places where intelligence indicated the possible presence of hostages"".
