In Nasser Hospital, southern Gaza’s main health facility, authorities are reported to have recovered a further 35 bodies from what they say is one of at least three mass graves found at the site, taking the total found there to 310 in the past week.

Palestinians say Israeli troops buried corpses there with bulldozers, Reuters reported.

Volker Turk, the United Nations human rights chief, has said he is “horrified” by the destruction of Nasser Medical Complex and al-Shifa Hospital in the Gaza Strip and reports of mass graves found in and around the hospitals.

Turk called for independent and transparent investigations after Palestinian authorities said this week they had recovered hundreds of bodies at Nasser Hospital following the withdrawal of Israeli troops from the city earlier this month.
