The United Nations, United States and Canada have appealed for a humanitarian pause in the Israel-Hamas war to allow safe deliveries of aid to civilians stricken by shortages of food, water, medicine and electricity in the Israeli-besieged enclave.
International pressure for unimpeded aid to Gaza rose as the health ministry in the Hamas-ruled territory reported that Israeli air strikes had killed more than 700 Palestinians overnight.
Ministry spokesman Ashraf Al-Qidra said this was the highest 24-hour death toll in Israel's two-week-old siege.
UN agencies were pleading "on our knees" for emergency aid to be let into Gaza unimpeded, saying more than 20 times current deliveries were needed to support the narrow strip's 2.3 million people amid widespread devastation from Israel's aerial blitz.
The United States is negotiating with Israel, neighbouring Egypt and the UN to smooth emergency deliveries into Gaza, but have wrangled over procedures for inspecting the aid and bombardments on the Gaza side of the border.
In a statement released on social media, the Palestinian health ministry said at least 5,791 Palestinians had been killed by Israeli bombardments since 7 October, including 2,360 children.
Some 704 were killed in the previous 24 hours alone, it said.
Reuters could not independently verify the ministry figures.
The Israeli military said that it killed dozens of Hamas fighters overnight while hitting over 400 Hamas targets, but that it would take time to destroy the Islamist militant group whose deadly cross-border attack stunned Israel.
UN Secretary-General Antonio Guterres pleaded for civilians to be protected, voicing concern about "clear violations of international humanitarian law" in Gaza.
US Secretary of State Antony Blinken, speaking to the UN Security Council, called for "humanitarian pauses" to enable urgent aid shipments to Gaza civilians.
"Palestinian civilians are not to blame for the carnage committed by Hamas," Mr Blinken said, referring to the militants' killing of 1,400 people, mainly civilians, and capture of more than 200 in a one-day rampage through Israeli communities near Gaza.
"Palestinian civilians must be protected. That means Hamas must cease using them as human shields ... It means Israel must take all possible precautions to avoid harm to civilians," Mr Blinken said.
Canadian Prime Minister Justin Trudeau echoed Mr Blinken.
"There are a lot of conversations going on now about the need for humanitarian pauses and I think that's something Canada supports," he told reporters in Ottawa.

The World Health Organization, in the latest of increasingly desperate UN appeals, called for "an immediate humanitarian ceasefire" to prevent food, medicines and fuel supplies from running out in Gaza.
Doctors in Gaza say patients arriving at hospitals are showing signs of disease caused by overcrowding and poor sanitation after more than 1.4 million people fled their homes for temporary shelters under Israel's heaviest-ever bombardment.
All hospitals say they are running out of fuel to power their electricity generators, leaving them increasingly unable to treat the injured and ill. More than 40 medical centres have halted operations, a health ministry spokesman said.
UNRWA, the UN agency for Palestinian refugees, warned in a post on messaging platform X that it would halt operations in Gaza tomorrow night because of the lack of fuel.
However, the Israeli military reaffirmed it would not permit the entry of fuel to prevent Hamas from seizing it.
The UN said 20 trucks that had been due to deliver aid to Gaza via the Rafah crossing from Egypt on today could not do so, but it hoped the convoy would get in on tomorrow.
Macron appeals to Israel
French President Emmanuel Macron, visiting Israel today, told Prime Minister Benjamin Netanyahu that France stood "shoulder to shoulder" with Israel in its war with Hamas, but that it must not fight "without rules".
Mr Netanyahu said Israel would try to protect civilians as it worked to ensure they "will no longer live under Hamas tyranny".
There appeared to be little prospect of a ceasefire any time soon in the bloodiest chapter of the Israeli-Palestinian conflict for decades, with civilian suffering spreading.
Asked about the difference between a humanitarian pause and ceasefire, White House spokesman John Kirby told reporters: "It's a question of duration and scope and size and that kind of thing."
After an air strike in Khan Younis in south Gaza, Abdallah Tabash held his dead daughter Sidra, refusing to let go as he held her bloodstained face and hair.

Live developments as they happen
'I went through hell', says freed Israeli hostage
"I want to look at her as much as I can," he said.
Israeli tanks and troops are massed on the border between Israel and Gaza awaiting orders for an expected ground invasion.
It is an operation that may be complicated by fears for the hostages' welfare and by militants heavily armed by Iran dug into a crowded urban setting using a vast network of tunnels.
'I've been through hell’
Hamas yesterday freed two Israeli women who were among the more than 200 hostages taken by gunmen during their mass infiltration on 7 October - the third and fourth to be released.
One of those freed, Yocheved Lifshitz, aged 85, said she was beaten by militants as she was abducted and had difficulty breathing.
"They stormed into our homes. They beat people. They kidnapped others, the old and the young without distinction," she said, seated in a wheelchair and speaking in barely a whisper to reporters outside a Tel Aviv hospital.
"I've been through hell," Ms Lifshitz said.
Inside Gaza, a group of hostages were led into what Ms Lifshitz called a "spider's web" of damp tunnels and eventually reached a large hall where, under 24-hour guard, a doctor visited every other day and brought them medicine that they needed.
Concern over conflict spreading
How soon Israel might launch a full-scale invasion of Gaza remains unclear. The Middle East's most powerful military faces a group that has developed a powerful arsenal with Iran's help.
World powers are concerned the conflict could ignite the entire Middle East and some have urged Israel to exercise restraint, while affirming its right to self-defence.
Deadly clashes have escalated between the Israeli military and Palestinians in the occupied West Bank, and resurged between Israel and Lebanon's Iran-backed, heavily armed Hezbollah group along the two countries' tinderbox border.
Fears of regional escalation focus on Iran's network of proxies in Syria, Iraq and Yemen. Any wider conflagration would jeopardise security in a region key to global energy supplies.
Mr Blinken also told the UN Security Council this evening that Washington does not seek conflict with Iran, but warned it would act swiftly and decisively if Tehran or its proxies attacks US personnel anywhere.
