Despite intense international pressure for a ceasefire to ease hunger and appalling conditions in the besieged Palestinian enclave, efforts to mediate a truce between Israel and the Palestinian militant group Hamas have collapsed.
Eight more people died of starvation or malnutrition in the past 24 hours, Gaza's health ministry said, while another 79 died in the latest Israeli firing.
The prime minister's office said, in a statement on Tuesday, that Netanyahu had held a "limited security discussion" lasting about three hours during which military Chief of Staff Eyal Zamir "presented the options for continuing the campaign in Gaza".
An Israeli official had earlier told Reuters that Defence Minister Israel Katz and Strategic Affairs Minister Ron Dermer, a confidant of Netanyahu, would also attend the meeting to decide on a strategy to take to the cabinet this week.
Israel's Channel 12, citing an official from Netanyahu's office, had said the prime minister was leaning towards taking control of the entire territory.
That would reverse a 2005 decision to withdraw from Gaza, while retaining control over its borders, a move right-wing parties blame for Hamas gaining power there.
It was unclear, however, whether Netanyahu was foreseeing a prolonged occupation or a short-term operation aimed at dismantling Hamas and freeing Israeli hostages.
The prime minister's office declined to comment on the Channel 12 report.
"It is still necessary to complete the defeat of the enemy in Gaza, release our hostages and ensure that Gaza never again constitutes a threat to Israel," Netanyahu told new recruits at a military base.
"We are not giving up on any of these missions."
On Saturday, Hamas released a video of Evyatar David, one of 50 hostages still held in Gaza, appearing emaciated in what seemed to be an underground tunnel.
The images shocked Israelis and sparked international condemnation.
Throughout the war, there has been sustained international pressure on Hamas to release the remaining hostages, of whom Israeli officials estimate 20 are still alive.
Most hostages have been released during ceasefires following diplomatic negotiations. Israel broke the last ceasefire.
A Palestinian official said the suggestion of a full takeover of Gaza may be a tactic to pressure Hamas into concessions, while the Palestinian Foreign Ministry urged foreign nations to take heed of the reports.
"The ministry urges countries and the international community to treat these leaks with utmost seriousness and to intervene urgently to prevent their implementation, whether these leaks are meant to exert pressure, test international reactions, or are genuine and serious," it said.
The war was triggered when Hamas-led militants attacked Israel on October 7, 2023, killing around 1200 people, mostly civilians, and capturing 251 hostages.
Israel's military response has devastated the tiny, crowded enclave, killing more than 61,000 people - mostly civilians - according to Palestinian health authorities.
Israel's campaign has forced nearly all of Gaza's more than two million people from their homes and caused what a global hunger monitor called last week an unfolding famine.
Some 188 Palestinians, including 94 children, have died from hunger since the war began, according to Gaza authorities.
On Tuesday, Israeli tanks pushed into central Gaza, but it was not clear if the move was part of a larger ground offensive.
Palestinians living in the last quarter of territory where Israel has not yet taken military control - via ground incursions or orders for civilians to leave - said any new push would be catastrophic.
"If the tanks pushed through, where would we go, into the sea? This will be like a death sentence to the entire population," said Abu Jehad, a Gaza wood merchant.
