The United States is doubling down efforts to reach a cease-fire deal as pressure mounts on Israeli Prime Minister Netanyahu.

Secretary of State Antony Blinken is traveling to Egypt, Israel, Jordan, and Qatar this week to discuss a cease-fire agreement that secures the release of all hostages, according to the State Department’s announcement Friday.

While Blinken traveling to the region should not be seen as a marker of further progress in reaching a deal, he will be putting pressure on the respective countries’ officials when he’s there.

A U.S. official told ABC News the intelligence that the U.S. provided to Israel in the latest hostage rescue operation was related to "support with locating individuals."

Currently, there are five American hostages the U.S. believes are still living and three that the U.S. has confirmed are deceased.

The White House is not commenting on the resignation of Centrist Israeli minister Benny Gantz on Sunday, as they don’t comment on domestic Israeli politics.

Centrist Israeli minister Benny Gantz announced Sunday that he was resigning from the emergency government because of what he has described as a lack of a plan from Israeli Prime Minister Benjamin Netanyahu for the "day after" in Gaza.

During a televised news conference, Gantz announced he was resigning from the coalition government, taking with him his State Party and the seats it held in the Knesset. Netanyahu's coalition government will still retain a majority, but the move by Gantz is considered a major blow to the prime minister.

"Netanyahu is preventing us from progressing towards a true victory," Gantz said. "For this reason, we are leaving the emergency government today, with a heavy heart, yet wholeheartedly."

He also called on Netanyahu to set a date for elections.

Gantz was set to make the announcement on Saturday but called it off amid the news of an Israel Defense Forces operation in Gaza that led to the rescue of four Israeli hostages.

Gantz is a member of Israel’s three-member war Cabinet, which includes Netanyahu and Defense Minister Yoav Gallant.

On Saturday, Netanyahu appealed to Gantz on X, saying, "This is the time for unity and not for division. We must remain united within ourselves in the face of the great tasks before us. I call on Benny Gantz -- do not leave the emergency government. Don't give up on unity."

Following Gantz's resignation, Netanyahu released a statement on X, saying, "Israel is in an existential war on several fronts."

"Benny, this is not the time to abandon the campaign -- this is the time to join forces," Netanyahu said. "Citizens of Israel, we will continue until victory and the achievement of all the goals of the war, primarily the release of all our hostages and the elimination of Hamas."

Netanyahu added, "My door will remain open to any Zionist party that is ready to get under the stretcher and assist in bringing victory over our enemies and ensuring the safety of our citizens."

In May, Gantz issued an ultimatum to Netanyahu, saying he would resign if the prime minister did not approve a post-war plan by June 8, saying at the time, "While the Israeli soldiers show supreme bravery on the front, some of the men who sent them into battle behave with cowardice and irresponsibility."

President Joe Biden issued a statement Sunday commemorating the Muslim holy day of Eid al-Adha in which he acknowledged the pain and suffering of innocent civilians in Gaza.

"In Gaza, innocent civilians are suffering the horrors of the war between Hamas and Israel.," Biden said. "Too many innocent people have been killed, including thousands of children. Families have fled their homes and seen their communities destroyed. Their pain is immense."

Biden added that his administration is working to end the war and make progress toward a two-state solution.

"And I strongly believe that the three-phase ceasefire proposal Israel has made to Hamas and that the U.N. Security Council has endorsed is the best way to end the violence in Gaza and ultimately end the war," Biden said.

Biden also cited the conflict in Sudan as well as the targeting of Muslim communities in Burma and China.

He used the holiday to celebrate the contributions of the Muslim community in America and also to say that he is committed to fighting Islamophobia in the United States.

"Hate has no place in America, whether it is targeted at American Muslims, Arab Americans including Palestinians, or anyone else," Biden said.

He added, "In the spirit of Eid al-Adha, let us all renew our commitment to values that unite us -- compassion, empathy, and mutual respect -- which are both American and Islamic."
