“What message would it send Hamas,” to cede under pressure following the deaths of more hostages, Mr. Netanyahu asked rhetorically. “Slay hostages and you’ll get concessions?”

Asked how he would define the end of the war, he said, “When Hamas no longer rules Gaza.”

His comments came after thousands of primary schools and several municipalities, transport networks and hospitals slowed or suspended operations across Israel on Monday, as work stoppages and protests formed the broadest expressions of anti-government dissent since the war in Gaza began.

A day after the Israeli military announced that it had recovered the bodies of six hostages from Gaza, union chiefs and business leaders joined forces in an effort to pressure Mr. Netanyahu to agree to a truce with Hamas. President Biden added to the pressure when he said Mr. Netanyahu was not doing enough to bring the hostages home, and Britain said it would suspend some weapons exports to Israel.

Here are the latest developments:

• Labor strikes pause: Union leaders agreed to halt the labor strike at 2:30 p.m. local time, more than eight hours after it began, after a court said they had not given enough notice for the work stoppage to go ahead. Disruptions were widespread, even as the strike’s effects appeared to be limited in some sectors. Many schools and banks and some municipal offices closed or cut services. But many municipalities continued work as normal, according to the representative body for local authorities, and some transport services returned by the afternoon.

• National fury: The work stoppage reflected the national outpouring of grief, anger and protest over the weekend. Advocates for the hostages and critics of Mr. Netanyahu argued that a cease-fire agreement could have saved the lives of the six hostages found dead in Gaza on Saturday. Huge street protests across Israel erupted on Sunday night in which hundreds of thousands of demonstrators, according to organizers, called for a hostage release and a cease-fire.

• Britain’s pressure: Britain announced that it will suspend the exports of some weapons to Israel, a significant hardening of its position on the war in Gaza. Foreign Secretary David Lammy said the decision was based on a legal review that concluded there was a “clear risk” the weapons could be used in a way that would breach international law. The suspension would affect 30 of 350 British export licenses and was “not an arms embargo,” he said. But the decision further distances Britain from the United States, which has rejected calls to suspend arms shipments to Israel. President Biden and Vice President Kamala Harris met at the White House on Monday morning with the team representing the United States in the talks.

• Hostages killed: The Israeli military said on Sunday that the six bodies found in Gaza were those of hostages who had been “brutally murdered” by Hamas. The Israeli Health Ministry later said that a forensic examination showed the hostages had been recently shot at close range. Hamas claimed, without providing evidence, that the hostages had been killed by the Israeli military. A funeral for one of the hostages, Hersh Goldberg-Polin, an Israeli American dual citizen whose parents were among the most prominent campaigners for their release, was held in Jerusalem.

• Polio in Gaza: Polio vaccinations continued for a second day in Gaza, after the Gazan Health Ministry said that more than 72,600 children had been vaccinated on Sunday in the central part of the territory. (United Nations agencies gave a higher figure, saying that nearly 87,000 had received the vaccine.) After Gaza last month recorded its first polio case in 25 years, Israeli forces and Hamas agreed to brief pauses in fighting to allow for a staggered, three-phase vaccination drive.
