Health authorities in Gaza have said at least 75 people have been killed in Israeli attacks in the last 24 hours, including 17 people seeking aid.
The enclave's health ministry also reported a further three deaths from malnutrition.
More Palestinian families have left Gaza City after a night of Israeli shelling on its outskirts.
Gaza City residents said that Israeli aerial and tank shelling continued throughout last night and early this morning in the eastern suburbs of Sabra, Shejaia, and Tuffah, as well as in Jabalia to the north, destroying houses and roads.
"Earthquakes, we call it, they want to scare people to leave their homes," said Ismail, 40, who lives in the city.
Around half of the enclave's two million people currently live in Gaza City, with several thousand already moved westward, pouring into the heart of the city and along the coast.
Others have ventured further south to central Gaza and the coastal area of Al-Muwasi near Khan Younis.
Despite widespread protests in Israel and international condemnation, the Israeli attacks continue, in what Israeli officials describe as the last bastion of Hamas.
Israeli strikes at Nasser Hospital in southern Gaza yesterday killed at least 20 people, including five journalists. The European Commission called the attack "completely unacceptable".
"Civilians and journalists must be protected under international law," Commission spokesperson Anouar El Anouni said at a press briefing.
In a statement today, the Israeli military claimed its troops had identified a camera positioned by Hamas near the hospital to observe its forces.
It claimed the striking and removing of the camera was the justification for the attack, which killed at least 20 people, including journalists.
"The Chief of the General Staff added that six of the individuals killed were terrorists," the IDF claimed in a statement.
Israel has repeatedly used claims of targeting Hamas as justification for attacks which have killed thousands of civilians in Gaza.
An Israeli security official said that none of the five journalists killed were among the six individuals it claimed were members of Hamas or Islamic Jihad.
The Israeli military said its Chief of General Staff has instructed the examination of "gaps", including the authorisation process before the attack and the decision-making process.

Investigations and accountability over 'mere inquiries' - UN
A United Nations rights spokesman has called for accountability from Israel and for an investigation to be launched into yesterday's attack.
A report published by Action on Armed Violence (AOAV) this month showed that 88% of Israel's investigations into war crime allegations in Gaza were shut down or left unresolved.
Speaking to RTÉ’s Drivetime, UN Human Rights office spokesperson Thameen Al-Kheetan said Israel is responsible for achieving accountability because Israel is the occupying power.
Mr Al-Kheetan said it was Israel’s responsibility "first and foremost" for achieving accountability through independent and prompt investigations, not only through "mere inquiries".
He said these should establish the facts and determine those who are responsible for the killing of journalists and hold them to account.
"In international law, when a state is unable or unwilling to achieve accountability, there can be other international mechanisms, like the application of universal jurisdiction in other national courts in other countries," he said.
"Or there can be international courts that can look into these incidents."
Second strike filmed live on camera
Mr Al-Kheetan said there is a problem with regards to what Israel has been doing in investigations when incidents were caught on camera.
"We don't see any accountability or rectifying these measures," he said.
Mr Al-Kheetan said most of the investigations are fact-finding inquiries, which are done by the military advocate general, who is also the legal advisor for the Israeli army.
He described this as a "conflict of interest" and said Israel is "yet to show us that its investigations will yield results".
"Also, it highlights the importance of the very crucial work that journalists are doing in Gaza in documenting all these incidents and telling us the stories of what is happening.

"In the event of yesterday, we see that the second strike was filmed on the camera of a journalist live," he said.
"We can today fear a moment where there would be no journalists to film such events and to document and to tell the whole world the horrible stories that are going on in Gaza."
A doctor who works at the Nasser Hospital in Gaza said he believes that journalists who were killed in the attack were deliberately targeted.
Dr Ahmed Al Farra, who is Head of the Paediatric and Maternity Department at Nasser Hospital, said that what happened was "unbelievable" as the attackers "know who's where in that area".
Meanwhile, Israeli protesters blocked roads in Tel Aviv and elsewhere in the country, holding up pictures of hostages still held in Gaza and calling for the war to end.
A rally planned outside Israel's defence headquarters was expected to draw thousands of people.
"For 690 days, the government has been waging a war without a clear objective," said Einav Zangauker, mother of Israeli hostage Matan Zangauker, in a statement with other families who launched the so-called Day of Disruption.
"How will the hostages, the living and the fallen, be returned? Who will govern Gaza the day after? How do we rebuild our country?" she asked.
Israeli attacks have killed at least 62,000 Palestinians, mostly civilians, according to the Gaza health ministry, plunged the enclave into a humanitarian crisis and internally displaced nearly its entire population.
The war began on 7 October 2023 when Hamas-led gunmen entered southern Israel, killing 1,200 people, mainly civilians, and taking 251 hostages, according to Israeli figures.
