Benjamin Netanyahu spoke with US President Donald Trump about Israel's new Gaza offensive plans, the Israeli prime minister's office has said.
"The two discussed Israel's plans to take control of the remaining Hamas strongholds in Gaza to bring an end to the war, by securing the release of the hostages and defeating Hamas," Mr Netanyahu's office said.
Earlier, Mr Netanyahu hit back at the wave of criticism targeting his cabinet's decision to expand the war in Gaza, saying the country was prepared to fight without the support of others.
"We will win the war, with or without the support of others," he said.
He said his country had no choice but to "complete the job" and defeat Hamas.
Israel's military said it has killed Al Jazeera journalist Anas Al-Sharif in a strike on Gaza City.
Al Jazeera has said that four journalists were killed in an Israeli strike on Gaza and confirmed Mr-Al Sharif's death.
"Al Jazeera journalist Anas al-Sharif has been killed alongside three colleagues in what appears to be a targeted Israeli attack, the director of the al-Shifa hospital in Gaza City has said," the Qatar-based broadcaster said.
"Al-Sharif, 28, was killed on Sunday after a tent for journalists outside the main gate of the hospital was hit.
"The well-known Al Jazeera Arabic correspondent reported extensively from northern Gaza."
The Israeli military accused Mr Al-Sharif of heading a Hamas cell.

Mr Netanyahu said that the new operation set to be launched by the military in Gaza will be on a "fairly short timetable".
"I don't want to talk about exact timetables, but we're talking in terms of a fairly short timetable because we want to bring the war to an end," he said.
The prime minister said the military had been given the greenlight to "dismantle" two remaining Hamas strongholds in Gaza City and Al Mawasi further to the south.
"We have about 70 to 75% of Gaza under Israeli control, military control.
"But we have two remaining strongholds, OK? These are Gaza City and the central camps in Al Mawasi," Mr Netanyahu told reporters.
Hamas slammed Israeli Mr Netanyahu for telling what it called a "series of lies" at the press conference.
"Netanyahu continues to lie, deceive and try to mislead the public. Everything Netanyahu said in the press conference is a series of lies, and he cannot face the truth; instead, he works on distortion and hiding it," Taher al-Nunu, the media adviser to the head of Hamas's political bureau said.
Meanwhile, thousands took to the streets in Tel Aviv last night to call for an end to the war in Gaza, a day after the Israeli government vowed to expand the conflict and capture Gaza City.
Demonstrators waved signs and held up pictures of hostages still being held in the Palestinian territory as they called on the government to secure their release.
Authorities did not provide an official estimate for the size of the crowd, though it dwarfed other recent anti-war rallies.
"We will end with a direct message to Prime Minister Benjamin Netanyahu: if you invade parts of Gaza and the hostages are murdered, we will pursue you in the town squares, in election campaigns and at every time and place," Shahar Mor Zahiro, the relative of a slain hostage, said.
On Friday, Mr Netanyahu's security cabinet greenlighted plans for a major operation to seize Gaza City, triggering a wave of domestic and international criticism.
Foreign powers, including some of Israel's allies, have been pushing for a negotiated ceasefire to secure the hostages' return and help alleviate a humanitarian crisis in the Palestinian territory.
Despite the backlash and rumours of dissent from senior Israeli military officers, Mr Netanyahu has remained defiant over the decision.
In a post on social media late on Friday, he said "we are not going to occupy Gaza -- we are going to free Gaza from Hamas".
He has faced regular protests over the course of 22 months of war, with many rallies calling for the government to strike a deal after past truces saw hostages exchanged for Palestinian prisoners in Israeli custody.
Out of 251 hostages captured during Hamas's 2023 attack, 49 are still being held in Gaza, including 27 the military says are dead.
The Palestinian Authority (PA) criticised Israel's plan to expand its operations in Gaza.
According to a statement carried by the official Palestinian news agency Wafa, President Mahmud Abbas said the plan "constitutes a new crime", and stressed "the urgent need to take action to stop it immediately".
He also emphasised "the importance of enabling the State of Palestine to assume its full responsibilities in the Gaza Strip".
In the same meeting that approved the Gaza City plan, the security cabinet adopted a set of principles for ending the war in Gaza that included establishing a new "administration that is neither Hamas nor the Palestinian Authority".
The PA, conceived as a first step towards a Palestinian state, exercises limited administration over parts of the Israeli-occupied West Bank, but does not have a presence in Hamas-run Gaza.
A statement issued yesterday by the foreign ministers of the UK, Italy, Australia, Germany, New Zealand again criticised the decision to occupy Gaza City.
"This will exacerbate the catastrophic humanitarian situation, endanger the lives of hostages, and increase the risk of a mass exodus of civilians," they said.
Russia also condemned the Israeli plan to take control of Gaza City in a statement.
Implementing such plans "risks worsening the already dramatic situation in the Palestinian enclave, which shows all the signs of a humanitarian disaster", said a foreign ministry statement.
Gaza's civil defence agency said at least 37 people were killed by Israeli fire across the territory yesterday, including 30 civilians who were waiting to collect aid.
Israel's offensive has killed more than 61,000 Palestinians, according to Gaza's health ministry, figures the United Nations says are reliable.
Hamas's 7 October 2023 attack on Israel - which triggered the war - resulted in the deaths of 1,219 people, according to an AFP tally based on official figures.
