Here’s the latest on the agreement.

A security cabinet vote that had been expected on Thursday was delayed amid last-minute disputes with Hamas and rifts over the agreement that emerged inside Mr. Netanyahu’s governing coalition.

Mr. Netanyahu’s announcement suggests that a cease-fire could still come into effect by this weekend. Secretary of State Antony J. Blinken had said on Thursday that he was confident the agreement would go into effect as planned on Sunday.

Late on Thursday, a vocal member of Mr. Netanyahu’s governing coalition took a stand against a cease-fire deal. Itamar Ben-Gvir, Israel’s hard-line national security minister, threatened to resign and remove his party from the Israeli government if the cabinet voted to approve the provisional deal, saying that it would leave Hamas in power in Gaza.

While Mr. Ben-Gvir’s threat could destabilize Mr. Netanyahu’s coalition at a critical time, it was unlikely to scuttle the cease-fire deal, which would also free hostages held by Hamas and Palestinian prisoners in Israel. Opposition lawmakers have pledged to support Mr. Netanyahu’s push for a cease-fire if more hard-line allies leave the coalition.

President-elect Donald J. Trump, who had pressured the parties to reach an agreement before his inauguration on Monday, repeated his warning in a podcast interview on Thursday that he wanted the deal closed before he took office on Monday. In December, weeks after he was re-elected, Mr. Trump said there would be “hell to pay” if a cease-fire and hostage deal was not reached.

Here’s what else to know:

• U.S. Support for Israel: President Biden, in his final television interview in office, which aired on MSNBC on Thursday night, defended his choice to steadfastly support Israel throughout the conflict, after he and his advisers struggled over many months of intense diplomatic efforts to finalize a cease-fire agreement.

• Attacks in Gaza: Deadly strikes have continued after the cease-fire deal was announced. The Palestinian Civil Defense, an emergency service organization, said that Israeli strikes had killed at least 77 people since the deal was announced. The claims could not be independently verified. The Israeli military said on Thursday that it had struck about 50 targets across the Gaza Strip over the past day, adding that “numerous steps” were taken to prevent civilian harm before the strikes.

• Cautious hope: Many Gazans reacted with wary hope mixed with sadness, exhaustion and fear. “How can we ever rebuild?” asked Suzanne Abu Daqqa, who lives near the southern city of Khan Younis. “Where will we even begin?” In Israel, the joy and relief that families of hostages expressed has been matched with anxiety that many could be left behind.

“I feel betrayed by the state of Israel,” said Efrat Ashkenazi-Hershkovitz, 50, whose brother died fighting in Gaza. “This deal will free people with blood on their hands,” she added, referring to the Palestinian prisoners expected to be released by Israel under the agreement.

For hours, the demonstrators, some teenagers, disrupted traffic in Jerusalem. They threw rocks onto highways, and clashed with police officers attempting to clear them.

In the evening, a few hundred demonstrators gathered at a central junction near the Israeli parliament, where they displayed an exhibition of cardboard coffins draped in Israeli flags.

One demonstrator, Eliav Turjman, a rabbi from Yeruham, Israel, said the Hostages Families Forum — the lobby representing the families of the hostages that has pushed for a cease-fire and hostage release deal — “appealed to Israelis’ hearts instead of their reason, which would dictate that we should occupy Gaza and expel its residents.”

Another reporter was ejected from the room at the start of a rare appearance there by Mr. Blinken, who had come to summarize his four-year tenure and take final questions from reporters.

At the news conference, Mr. Blinken said that, despite reports of last-minute snags, he was “confident” that the cease-fire deal reached this week by Hamas and Israel would begin to be carried out on Sunday as planned.

Mr. Blinken otherwise covered largely familiar subject matter as he fielded questions largely focused on criticism of the Biden administration’s continued supply of weapons to Israel as Palestinian casualties mounted, with Mr. Blinken noting that Hamas embedded itself among civilians. “Some people say we did too much to restrain Israel,” he said. “Others say we did too much to enable.”

But the news conference was most memorable for the outbursts that punctured Mr. Blinken’s opening remarks, the likes of which, Aaron David Miller, a former longtime diplomat, said on X he had never seen.

The man picked up from his seat and carried away by several security officers was Sam Husseini, who identifies himself online as “an independent journalist and writer who has been piercing through the establishment’s falsifications for 25 years” and is known for his confrontational questions at department briefings.

The other reporter was Max Blumenthal, a prominent left-wing journalist and fierce critic of Israeli policies, who asked Mr. Blinken, “How does it feel to have your legacy be genocide?”

Then, referring to Prime Minister Benjamin Netanyahu of Israel, he added, “You waved the white flag before Netanyahu!”

Such invective is by now all too familiar to Mr. Blinken, who most recently was shouted down and called a war criminal by protesters during remarks he gave on Gaza at a Washington think tank this week. In each case Mr. Blinken was largely unfazed, and continued his remarks once calm had returned to the room.
