“Civil defense teams have dug up 392 bodies from the mass graves,” the agency said during a press conference in the southern city of Rafah.

Bodies of children were found among the victims.

“We don’t know the reason for the presence of children’s bodies in mass graves at the hospital,” the agency added.

According to the agency, signs of torture were found on the bodies of the victims.

“There are indications of carrying out field executions against some of the victims, while the bodies of other victims carried signs of torture and others were buried alive,” it said.

“Several victims were buried in plastic bags and placed at a depth of three meters, which accelerated their decomposition,” it added.

The bodies were discovered after the Israeli army withdrew from Khan Younis on April 7 following a 4-month ground offensive in the city.

Israel has waged a brutal offensive on the Gaza Strip since a cross-border attack by the Palestinian group Hamas on Oct. 7 last year, which Tel Aviv says killed nearly 1,200 people.

More than 34,300 Palestinians have since been killed, mostly women and children, and 77,300 others injured, according to local health authorities.

More than six months into the Israeli war, vast swathes of Gaza lay in ruins, pushing 85% of the enclave’s population into internal displacement amid a crippling blockade of food, clean water and medicine, according to the UN.

Israel stands accused of genocide at the International Court of Justice. An interim ruling in January ordered Tel Aviv to stop genocidal acts and take measures to guarantee that humanitarian assistance is provided to civilians in Gaza.

The Euro-Mediterranean Human Rights Monitor has also joined numerous rights groups and nations in calling for an independent investigation into the discovery of dozens of mass graves in Gaza.

It said its team members on the ground had witnessed the exhumation of hundreds of bodies found in the vicinity of Gaza City’s al-Shifa Hospital and saw victims “handcuffed … who were executed”.

In a statement, Euro-Med announced the high number of bodies that have been recovered is “alarming, and requires urgent international action, including the formation of an independent international investigation committee”.

Many of those who lost their lives were subjected to “premeditated murder as well as arbitrary and extrajudicial executions while they were detained and handcuffed”, it added.

This news comes after Germany announced today that it would restore its funding to the agency, which it froze in January amid allegations by Israel that UNRWA staff had participated in the October 7 attacks on Israel. This week, a report from Catherine Colonna, former French foreign minister, discredited the Israeli allegations.

“Political sources in Israel have acknowledged in talks with foreign diplomats in recent days that Jerusalem had not succeeded in influencing the report in the way it had hoped,” Haaretz daily reported.

“An Israeli source involved in the diplomatic effort to halt funding to UNRWA told Haaretz that the failure was not in the field of public relations and communications, but rather stemmed from the lack of a convincing alternative to UNRWA,” it added.

Philippe Lazzarini, head of UNRWA, has told Al Jazeera that Israel’s campaign to discredit and defund the organisation had led to it facing an “unprecedented” crisis.

UNRWA plays a vital role in distributing desperately needed aid inside Gaza, where thousands are facing famine.

UNRWA has been hindered from doing its job since January, when Israel accused a handful of its thousands of employees of being involved in the Hamas attacks on Israel.

Amid a probe of the claims, several countries have cut off funding to the agency, and its aid work for Gaza’s famine-stricken population has suffered.

At least 18 countries initially suspended funding to the agency amid the allegations.

UNRWA was created by the UN General Assembly more than 70 years ago to assist Palestinians who were forcibly displaced from their land.

The agency provides crucial support to millions of Palestinian refugees in the Gaza Strip, West Bank, Jordan, Lebanon, Syria and other areas where large numbers of registered Palestinians live.
