The World Health Organization (WHO) has described al-Shifa hospital in Gaza City as a “death zone” after a visit to the complex.
A joint UN team led by the WHO assessed the hospital for one hour following its occupation and evacuation by the Israeli military.
The team said they saw evidence of shelling and gunfire and observed a mass grave at the hospital’s entrance.
They were told it held the remains of 80 people.
Following an evacuation which the hospital director said was ordered by the Israeli army but which the army said was requested by the director, 300 critically ill patients remain in al-Shifa – formerly the largest and most advanced hospital in Gaza.
The WHO said it was trying to arrange the urgent evacuation of remaining patients and staff to other facilities in Gaza, and repeated calls for a ceasefire.
Meanwhile, the White House has responded to a report in the Washington Post which said Israel, Hamas and the US were on the verge of a deal that would see the release of women and children seized by Hamas on 7 October in exchange for a five-day pause in fighting.
A White House spokesperson said no such deal had yet been reached but it was working hard to get one agreed.
Israel’s Prime Minister, Benjamin Netanyahu, has ruled out a full ceasefire with Hamas and said he will consider only a temporary truce in exchange for the return of hostages kidnapped by the group.
