The UN on Monday described the reports of mass graves in Gaza as "extremely troubling" and urged for an investigation into the sites where the grave is located.
"Yet another reason is, if we needed one, for all of these sites to be fully investigated, in a way that is credible and independent," Spokesman Stephane Dujarric said at a press briefing when asked about the uncovering of at least 283 bodies of people from a mass grave at the Nasser Hospital in the southern city of Khan Younis.
Gaza's Civil Defence agency said Monday that health workers had uncovered over 200 bodies in the past three days of people killed and buried by Israeli forces at a hospital in Khan Younis.
When asked for comment, the Israeli military said: "We will come back to you on the matter."
Mahmud Bassal, spokesman for Gaza's Civil Defence, told AFP that "civil defence crews are still recovering bodies from inside Nasser Medical Complex, and since Saturday bodies of nearly 200 martyrs have been retrieved".
Bassal said several of the recovered bodies had decomposed.
Hospitals in Gaza have not been spared in the Israeli assault since October 7. Tlaleng Mofokeng, the United Nations special rapporteur on the right to health, says Israel's war has from the start been a "war on the right to health" and has "obliterated" the Palestinian territory's health system.
More than 34,000 people have been killed in the enclave, mostly women and children, with over 77,000 wounded and thousands more missing.
