US Secretary of State Antony Blinken has warned Prime Minister Benjamin Netanyahu that Israel risks further global isolation if it goes ahead with plans for a ground assault on the Palestinian city of Rafah in Gaza.
Mr Blinken met one-on-one with Mr Netanyahu during a peace mission to the Middle East at a time of strain in relations over Israel's assault in Hamas-ruled Gaza.
"We share Israel's goal of defeating Hamas... though, a major military ground operation in Rafah is not the way to do it," Mr Blinken told reporters in Tel Aviv.
"It risks killing more civilians, it risks wreaking greater havoc with the provision of humanitarian assistance, it risks further isolating Israel around the world and jeopardising its long-term security and standing," Mr Blinken added.
Mr Netanyahu said earlier that Israel would go it alone if Washington remained opposed to plans to push into Rafah against the territory's southern border fence, where more than a million Gazans have taken refuge in makeshift shelters.
The Israeli leader said he told Mr Blinken that he appreciated US support in its fight against Hamas, the Palestinian militant group, and that Israel recognises it needs to protect civilians.
"I also said that we have no way to defeat Hamas without going into Rafah and eliminating the rest of the battalions there. And I told him that I hope we will do it with the support of the US, but if we have to - we will do it alone," he said in a video statement to reporters.
Israel says Rafah is the last bastion for Hamas militants, and that it has a plan to evacuate civilians before an attack. Washington says a ground assault would be a mistake and cause too much harm to those displaced there.
Senior Israeli and US officials are scheduled to meet in Washington next week, when the United States will present to the Israelis alternative ways to hunt down Hamas without resorting to a full-on assault in Rafah.
The United States, Israel's closest ally, provides billions of dollars a year in military aid and regularly uses its diplomatic clout to protect Israeli interests.
In the latest diplomatic duel at the UN Security Council, Russia and China vetoed a US-proposed resolution calling for an immediate ceasefire in Gaza and an Israel-Hamas hostage deal.
The text reflected a toughening of Washington's stance toward Israel - Washington had earlier in the war been averse to the word "ceasefire" - but Moscow and Beijing said it would still not do enough to restrain Israel.
They support an alternative text that Washington says is not strong enough in pushing Hamas towards ongoing diplomacy.
France was also said to be working on an alternative resolution. The Security Council is due to vote again tomorrow.
In Gaza, Israel today claimed to have killed or captured hundreds of Hamas fighters in a five-day operation at the Al Shifa hospital complex, one of the only medical facilities even partially functioning in the north. Hamas and medical staff deny fighters were present there.
Strain in relations
A strain in ties between the United States and Israel has become increasingly public, with US President Joe Biden calling Israel's campaign in Gaza "over the top" and saying it has had too great a toll on civilian lives.
The war was triggered by a raid into southern Israel by Hamas fighters who killed 1,200 people and took 253 hostages, by Israeli tallies.
More than 32,000 Palestinians have been killed in the subsequent Israeli assault, with many more feared dead under the rubble, Gaza health authorities say.
US officials say the number of aid deliveries via land needs to increase fast and that aid needs to be sustained over a long period.
Israel, which inspects all shipments to Gaza and has sealed off the fence on the north of the enclave, denies restricting food and says it believes enough is getting through.
"As much as we know, by our analysis, there is no starvation in Gaza. There is a sufficient amount of food entering Gaza every day," Colonel Moshe Tetro, head of Israel's Coordination and Liaison Administration for Gaza, told reporters.
Airstrike kills eight
Eight people were killed today in an airstrike on a house in Al-Naser, east of Rafah. Video images showed crowds of mourners around white shrouded corpses, while a red rag doll lay in the rubble of a crushed house.
The dead included a father, a mother and five of their children, said mourner Turkiah Barbakh.
"They are all children; they haven't resisted or done anything. What happened to them is unjust," she said.
"How much longer do we have to endure this?"
Vice President Kamala Harris said there was no safe exit for civilians from Rafah.
Meetings took place in Doha today aimed at securing a ceasefire. The truce talks are focused on a proposal for a six-week halt to fighting during which some 40 Israeli hostages being held by Hamas would be released in exchange for hundreds of Palestinians in Israeli jails.
Israel is prepared to commit only to a temporary pause in fighting, while Hamas wants a permanent end to the war.
Israel said it had killed hundreds of fighters and detained more than 500 suspects in its operation at Al Shifa, including 358 members of Hamas and Islamic Jihad.
It said three senior Islamic Jihad military commanders and two Hamas officials responsible for operations in the occupied West Bank were among those detained.
Hamas denies its fighters were in the compound and says civilians and medical staff were rounded up.
