Israeli attacks have killed at least 32 people across Gaza City, including 12 children, medical staff have said.
The morgue in Shifa Hospital, where the bodies were taken, confirmed there were 12 children among those killed.
One of the strikes overnight and into early this morning hit a house in the Sheikh Radwan neighbourhood, killing a family of ten, including a mother and her three children, health officials said.
Images showed the strikes hitting followed by plumes of smoke.
Israel has intensified strikes across Gaza City, destroying high-rise buildings and killed hundreds of Palestinians in the past week alone.
It has ordered residents to leave, part of an offensive aimed at taking over the largest Palestinian city, which it says is Hamas's last stronghold.
Hundreds of thousands of people remain there, struggling under conditions of famine.
The number of people leaving has risen in recent weeks, according to aid workers, but many families remain stuck because of the cost of finding transport and housing, while others have been displaced too many times and do not want to move again, not trusting that anywhere in the enclave is safe.
This morning, Israel’s army told the remaining Palestinians in Gaza City to leave immediately and move south to what it is calling a humanitarian zone.
Army spokesman Avichay Adraee claimed more than a quarter of a million people had left the city - from an estimated one million who live in that area of north Gaza.
The United Nations put the number of people who have left at more than 100,000 between mid-August and mid-September.
The UN and aid groups have warned that displacing hundreds of thousands of people will exacerbate the dire humanitarian crisis.
Sites in southern Gaza where Israel is telling people to go are overcrowded, according to the UN, and it can cost more than €850 in transport and other costs to move there.
An initiative headed by the UN to take temporary shelters into Gaza said more than 86,000 tents and other supplies were still awaiting clearance to enter as of last week.
WHO calls on countries to receive Gaza patients
Meanwhile, WHO chief Dr Tedros Adhanom Ghebreyesus called on countries to "open their arms" to receive critically ill patients from Gaza.
"In a post on X, Dr Tedros said the urgent problem is that too few countries are willing to receive them.
"We call for countries to open their arms to these critically ill patients. We call on Israel to allow people to be treated in the West Bank and East Jerusalem, where hospitals closer to home can take many patients."
.@WHO is doing all we can to alleviate suffering, and evacuate those who need urgent medical care outside Gaza.

The bombardment last night across Gaza City came days after Israel launched a strike targeting Hamas leaders in Qatar, intensifying its campaign against the militant group and endangering negotiations over ending the war in Gaza.
Families of the Israeli hostages still held in Gaza are pleading with the government to halt the offensive, worried it will kill their relatives.
There are 48 hostages still inside Gaza, around 20 of them believed to be alive.
Israeli attacks have killed more than 64,700 Palestinians, according to Gaza’s Health Ministry.
Large parts of major cities have been completely destroyed and around 90% of two million Palestinians have been displaced.
Global hunger monitor IPC determined this month that an entirely man-made famine is currently taking place in Gaza, while UN human rights chief Volker Turk said the famine was the direct result of Israeli government policies.
The world's biggest academic association of genocide scholars passed a resolution saying the legal criteria have been met to establish Israel is committing genocide in Gaza.
The current stage of the war in Gaza began when Hamas-led militants stormed into southern Israel on 7 October 2023, abducting 251 people and killing 1,200, mostly civilians, according to Israeli tallies.
