Benjamin Netanyahu will convene his security cabinet this week to decide on Israel's next steps in Gaza following the collapse of indirect ceasefire talks with Hamas, with one senior Israeli source suggesting more force could be an option.
Last Saturday, during a visit to the country, US Middle East envoy Steve Witkoff had said he was working with the Israeli government on a plan that would effectively end the war in Gaza.
But Israeli officials have also floated ideas including expanding the military offensive in Gaza and annexing parts of the shattered enclave.
Mr Netanyahu is leaning toward expanding the offensive in Gaza and seizing the entire enclave, Israel's Channel 12 cited an official from his office as saying.
The failed ceasefire talks in Doha had aimed to clinch agreements on a US-backed proposal for a 60-day truce, during which aid would be flown into Gaza and half of the hostages Hamas is holding would be freed in exchange for Palestinian prisoners jailed in Israel.
After Mr Netanyahu met Mr Witkoff last Thursday, a senior Israeli official said that "an understanding was emerging between Washington and Israel," of a need to shift from a truce to a comprehensive deal that would "release all the hostages, disarm Hamas, and demilitarize the Gaza Strip," - Israel's key conditions for ending the war.
A source familiar with the matter told Reuters yesterday that the envoy's visit was seen in Israel as "very significant."
But later, the Israeli official signalled that pursuit of a deal would be pointless, threatening more force: "An understanding is emerging that Hamas is not interested in a deal and therefore the prime minister is pushing to release the hostages while pressing for military defeat."
'Strategic clarity'
What a "military defeat" might mean, however, is up for debate within the Israeli leadership.
Some Israeli officials have suggested that Israel might declare it was annexing parts of Gaza as a means to pressure the militant group.
Others, like Finance Minister Bezalel Smotrich and National Security Minister Itamar Ben-Gvir want to see Israel impose military rule in Gaza before annexing it and re-establishing the Jewish settlements Israel evicted 20 years ago.
The Israeli military, which has pushed back at such ideas throughout the war, was expected to present alternatives that include extending into areas of Gaza where it has not yet operated, according to two defence officials.
While some in the political leadership are pushing for expanding the offensive, the military is concerned that doing so will endanger the 20 hostages who are still alive, the officials said.

Israeli Army Radio reported that military chief Eyal Zamir has become increasingly frustrated with what he describes as a lack of strategic clarity by the political leadership, concerned about being dragged into a war of attrition with Hamas militants.
A spokesperson for the Israel Defense Forces (IDF) declined to comment on the report but said that the military has plans in store.
"We have different ways to fight the terror organization, and that's what the army does," Lieutenant Colonel Nadav Shoshani said.
On Tuesday, Qatar and Egypt endorsed a declaration by France and Saudi Arabia outlining steps toward a two-state solution to the Israeli-Palestinian conflict, which included a call on Hamas to hand over its arms to the Western-backed Palestinian Authority.
Hamas has repeatedly said it will not lay down arms. But it has told mediators it was willing to quit governance in Gaza for a non-partisan ruling body, according to three Hamas officials.
It insists that the post-war Gaza arrangement must be agreed upon among the Palestinians themselves and not dictated by foreign powers.
Israel's Foreign Minister Gideon Saar suggested that the gaps were still too wide to bridge.
"We would like to have all our hostages back. We would like to see the end of this war. We always prefer to get there by diplomatic means, if possible. But of course, the big question is, what will be the conditions for the end of the war?" he said.
Israeli ex-security chiefs urge Trump to help end Gaza war
Meanwhile, hundreds of retired Israeli security officials including former heads of intelligence agencies have urged US President Donald Trump to pressure their own government to end the war in Gaza.
"It is our professional judgement that Hamas no longer poses a strategic threat to Israel," the former officials wrote in an open letter shared with the media.

"At first this war was a just war, a defensive war, but when we achieved all military objectives, this war ceased to be a just war," said Ami Ayalon, former director of the Shin Bet security service.
The war, nearing its 23rd month, "is leading the State of Israel to lose its security and identity," Mr Ayalon warned in a video released to accompany the letter.
Signed by 550 people, including former chiefs of Shin Bet and the Mossad spy agency, the letter called on Mr Trump to "steer" Mr Netanyahu towards a ceasefire.
Separately, Israel's ambassador to the UN has said that the UN Security Council will hold an emergency session tomorrow on the hostages in Gaza.
Danny Danon posted the announcement on social media amid anger over videos showing two of the hostages held by Palestinian militant group Hamas emaciated.
Mr Danon said that the Council "will convene this coming Tuesday for a special emergency session on the dire situation of the hostages in Gaza".
The videos make references to the humanitarian conditions in Gaza, where UN-mandated experts have warned a "famine is unfolding."
Israel has heavily restricted the entry of aid into Gaza, while UN agencies, humanitarian groups and analysts say that much of what Israel does allow in is looted or diverted in chaotic circumstances.
Many desperate Palestinians are left to risk their lives seeking what aid is distributed through controlled channels.

Yesterday, Mr Netanyahu requested the help of the International Committee of the Red Cross to get food to the hostages.
In response, Hamas's armed wing said that it would allow the agency access to the hostages but only if "humanitarian corridors" for food and aid were opened "across all areas of the Gaza Strip".
The Al-Qassam Brigades said it did "not intentionally starve" the hostages, but they would not receive any special food privileges "amid the crime of starvation and siege" in Gaza.
Over recent days, Hamas and its ally Islamic Jihad have released three videos showing two hostages seized during the 2023 attack on Israel.
The images of Rom Braslavski and Evyatar David, both of whom appeared weak and malnourished, have fuelled renewed calls in Israel for a truce and hostage release deal.
