National Unity party leader Benny Gantz slammed Israeli Prime Minister Benjamin Netanyahu on Tuesday, claiming he is holding up a cease-fire and hostage deal.

Gantz said that on Monday, Netanyahu in his speech "did not look directly at the public and told the truth: That he will not bring the kidnapped alive, that he will not truly protect the southern bracket, that he will not return the residents of the north to their homes, that he will not deny Iran nuclear weapons."

"This did not surprise me, because during the period that we sat in the War Cabinet, Netanyahu delayed the ability to move forward with the abducted deals serially, including in the first outline," Gantz said. "This does not surprise me because already at the beginning of the war, when we asked to extend the military pressure to Khan Yunis and then to Rafah, Netanyahu hesitated and stopped."

"The time has come to say yes and move forward: we need to bring a deal - either in stages or in one stage," Gantz said.

Netanyahu in response laid out the Israeli military's recent successes.

"Since Gantz and his party resigned from the government, Israel has eliminated the Hamas Chief of Staff and the Hezbollah Chief of Staff, attacked the Houthis, captured the Philadelphia axis - Hamas's armament pipeline - and carried out a pre-emptive strike against Hezbollah that thwarted its malicious plan and destroyed thousands of rockets aimed at the Galilee," Netanyahu said. "Whoever does not contribute to the victory and the return of our hostages, it is better not to interfere."

Thousands gathered in Tel Aviv Tuesday for a new protest organized by the Hostages and Missing Families Forum.

The event was led by the younger members of the Hostages and Missing Families Forum who are calling for a deal to bring all of the hostages home, the organization said.

Forty-three people have been killed from ongoing operations in the Gaza Strip on Tuesday, according to the Hamas-run Gaza Ministry of Health.

Israeli forces said its soldiers "struck a compound where Hamas terrorists were operating" and killed eight Hamas members. The strike was near the Al-Ahli hospital compound but wasn’t within the hospital premises, the IDF said.

"Prior to the strike, numerous steps were taken to mitigate the risk of harming civilians, including the use of precise munitions, aerial surveillance, and additional intelligence," the IDF said in a statement.

White House national security communications adviser John Kirby hedged on reports that the U.S. is putting forward a "final proposal" when it comes to hostage negotiations, saying the administration -- including President Joe Biden – is still working to get a deal.

Kirby refused to give any details about the current proposal, or how it might differ from previous offers put forward, but he stressed that the deal is "actively" being worked on with Qatar and Egypt.

"The president himself is personally involved in working with our team and working with leaders around the world to secure this deal,” Kirby said, adding that this weekend’s recovery of six slain hostages "underscores the sense of urgency that we have."

Asked about the United Kingdom’s new restrictions on some arms exports to Israel, Kirby said he would not "comment one way or another on the decisions that our British counterparts made."

U.K. Foreign Secretary David Lammy told Parliament on Monday about 30 of its 350 export licenses were suspended because "there does exist a clear risk that they might be used to commit or facilitate a serious violation of international humanitarian law."

"I can just tell you that, No. 1: We're going to continue to do we have to do to support Israel's defensive capabilities," Kirby said. “No. 2: We have, as I've said many times, reviewed individual reports as best we can, and talking to the Israelis about individual reports about compliance with international humanitarian law. And as we speak, there's been no determination by the United States that they have violated international humanitarian [law].”
