The announcement comes after the Israeli military raided one of the last functioning hospitals in northern Gaza, arresting its director.
Israel has been at war with Hamas for more than 14 months since the 7 October attacks in which around 1,200 people were killed and 250 others abducted.
More than 45,400 Palestinians, over half of them women and children, have been killed and more than 108,000 others wounded, according to the Hamas-run Palestinian health ministry, which does not distinguish between civilians and combatants.
Mr Netanyahu made the announcement after an “in-depth four-hour discussion in the political-security cabinet”.
He said the cabinet “all expressed outrage at the shocking situation of our three hostages who were released last Saturday”.
Mr Netanyahu said they passed a unanimous agreement: “If Hamas does not return our hostages by Saturday noon – the ceasefire will be terminated, and the IDF will return to intense fighting until Hamas is finally defeated.”
Donald Trump has emboldened Israel to call for the release of remaining hostages, rather than the three scheduled to be freed in the next exchange.
Mr Netanyahu said the cabinet “welcomed” Mr Trump’s demand for hostages to be released by midday Saturday, “and we all also welcomed the president’s revolutionary vision for the future of Gaza”.

Police investigating the deaths of a British couple at their home in rural France have released details from a post-mortem examination.
Prosecutors say Dawn Searle, 56, was found at their property in Les Pesquies with “several” injuries to her head, while her husband, Andrew Searle, 62, was found hanged with no visible defensive injuries.
They are investigating whether the deaths are the result of a murder-suicide or if a third party was involved.
The pair are said to have been found dead by a German friend, who lives nearby, on Thursday after Mr Searle didn’t arrive for one of their regular dog walks.
The couple moved to the hamlet of Les Pesquies around a decade ago and married in the nearby town of Villefranche-de-Rouergue, in the south of France, in 2023.

A statement from the office of public prosecutor Nicolas Rigot-Muller said Ms Searle was found partially dressed with a major wound to her skull next to a box with jewellery inside.
But no object or weapon was found that could’ve caused the wounds, which an autopsy carried out in Montpellier on Monday found were caused by a blunt and sharp object. There were no signs of sexual assault.
The house appeared to have been quickly searched, while some cash was found in the couple’s room.
Investigators are conducting further examinations, including toxicology and pathology tests, to help determine the precise circumstances of their deaths.

They each have two children from previous relationships and Ms Searle’s son, the country musician and former Hollyoaks star Callum Kerr, said they were in mourning in a statement posted on Saturday.
Family members are understood to have travelled to France, where they have spoken with investigators.
Speaking to Sky News from the town hall in which he conducted the couple’s wedding ceremony, he said: “It doesn’t seem like the problem comes from here because when we knew them and saw them living here they were very happy, very friendly and didn’t seem to have any problems.
“The problem seems to come from the past or somewhere far away.
“It’s an isolated act, it’s very independent. It doesn’t say that it’s a very dangerous territory, in fact, it’s very peaceful and that’s why probably Andy and Dawn chose to live here, because it’s very peaceful.
“Now, did their past come back and get them? That’s another story. That’s totally different from where we are. It could’ve happened anywhere.”
A Foreign Office spokesperson previously said: “We are supporting the family of a British couple who died in France and are liaising with the local authorities.”
