The UN human rights chief, Volker Türk, said he was "horrified" by reports of mass graves following sieges by the Israeli Defense Force (IDF) at two of Gaza's largest hospitals. Nasser Hospital recovered nearly 300 bodies and al-Shifa Hospital recovered over 380 bodies from mass graves. It was reported that some of the bodies had their hands tied, in violation of human rights laws. Some of the bodies were stripped of their clothing.

The IDF claims it raided the hospitals because Hamas was hiding in and around the medical facilities. Three medical staff told the BBC last month that they were humiliated, beaten, doused with cold water, and forced to kneel for hours after being detained during the raid.

Israeli PM Netanyahu has repeatedly threatened to attack Rafah, Gaza's southernmost city, where more than a million people are sheltering. 

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.
