Pan-Arab broadcaster Al Jazeera aired on Monday footage of a mass grave found on the grounds of Al-Shifa Hospital in Gaza City, two weeks after an Israeli army raid on the site.

A correspondent for the channel said that medical teams had found a “mass grave of Palestinians who were buried by the [Israeli] occupation troops in the yard of the Al-Shifa Medical Complex in Gaza”.

He said nine bodies had been recovered and that medical and civil defence personnel were still looking for corpses.

Al Jazeera reported that doctors and witnesses had said the bodies belonged to people Israeli forces had executed.

The channel also reported that “another mass grave of 20 people from the Assaf family was discovered” in the city of Beit Lahia in northern Gaza.

Al-Shifa, once the biggest hospital in all of Gaza, has faced two Israeli raids since the war on the strip began in October.

On Monday, the enclave’s health ministry issued a statement calling for the relevant institutions to create field hospitals in the territory’s north, including Gaza City. It said Al-Shifa and many hospitals were fully out of service.

Israel’s brutal war on Gaza has so far killed more than 33,800 people, according to the strip’s health ministry.

The Israeli military campaign has devastated Gaza’s infrastructure, with hospitals and residential homes attacked.

The International Court of Justice in January found that Israel was plausibly breaching the UN Genocide Convention in Gaza.
