President Joe Biden confirmed that he has pressed Israeli Prime Minister Benjamin Netanyahu for a three-day pause in Gaza. Biden said he's also asked for an even bigger window to get the remaining hostages out.

Biden told reporters his message to the families of hostages is: "We're not going to stop until we get them out."

Israeli officials say Hamas had 239 hostages in Gaza. Four hostages were released from Gaza over the last few weeks: two American women and two Israeli women. The Israel Defense Forces said a fifth hostage, a female Israeli soldier, was rescued during the Israeli military's ground operations in Gaza.

Asked if there would be a cease-fire, Biden responded, "None. No possibility."

CIA Director William Burns took part in a meeting in Qatar regarding a potential hostage deal, a U.S. official confirmed.

Burns also traveled to Egypt "where he met with his intelligence counterparts and country leaders," the official said. "They discussed issues of mutual concern, including the situation in Gaza and the USA commitment to ensuring humanitarian aid there."

A "general" cease-fire would benefit Hamas and "legitimize" the group's Oct. 7 surprise attack on Israel, U.S. National Security Council spokesperson John Kirby said Thursday.

"A general cease-fire means everybody lays your arms down and you talk about the end of this conflict," Kirby told ABC News' George Stephanopoulos on "Good Morning America." "To do that right now would be a benefit to hamas. It would give them time. It would also legitimatize what they did on October 7th."

He said Israeli military forces were in the middle of an "operational campaign" targeting Hamas leadership.

"We believe Israel has a right to do that and we'll continue to make sure they get the tools and capabilities," Kirby said.

But there may be a need for a "pause" if some of the about 240 hostages taken by Hamas are to be released, Kirby said

"What we want to make sure is not only can we secure their release, George, but that when we get that release secured, that we can get them safely out of Gaza and into Israel, into safer hands," he said. "That requires this idea of a temporary humanitarian pause."

About 72,000 people have fled northern Gaza in the last four days, moving south along a corridor opened by Israeli military forces, the United Nations said Thursday.

About 50,000 traveled along Salah al-Din Road in the hours the corridor was opened on Wednesday, the U.N. Office for the Coordination of Humanitarian Affairs said.

“Clashes and shelling on and around the road reportedly continued, endangering evacuees with reports of corpses alongside the road,” the U.N. statement said.

Many have arrived at the corridor on foot. Some who’ve driven there have been told to leave their vehicles along the outskirts of Gaza City, the U.N. said. Videos and photos released by the Israel Defense Forces have shown crowds marching while waving white flags.

“The evacuees then walk 4-5 kilometres down the corridor, with an estimated distance of up to 20 kilometres for those traveling farthest,” the U.N. said.

Fighting between Hezbollah and Israeli forces intensified Sunday in southern Lebanon, where the terrorist group has claimed responsibility for launching a series of missile strikes on northern Israel, Israeli military officials say.

“Hezbollah is dragging Lebanon into a war that may happen, and it is making mistakes," Israeli Defense Minister Yoav Gallant said on Saturday. “If it makes mistakes of this kind, the ones who will pay the price are first of all the citizens of Lebanon. What we are doing in Gaza we know how to do in Beirut."

Hezbollah has claimed responsibility for at least five attacks in northern Israel, including one it says resulted in numerous deaths and injuries. The terrorist group also claimed one of its missile strikes targeted Israel's Zarit Barracks on the Israeli-Lebanese border.

Hezbollah has been designated a terrorist organization by multiple countries, including the U.S. and Israel.

Fighting between Hezbollah and Israeli troops intensified Saturday night into Sunday. Local news media broadcast images of the heavy clashes in the hills along the border and smoke rising.

Lebanese Prime Minister Najib Mikati released a statement saying his country does not want war but has made a contingency plan in case it is drawn into the conflict between Israel and Hamas.

"What matters to me is that Lebanon stays away from war and looks forward to stability," Mikati told the Al Jazeera network.

During the Al Jazeera interview, Mikati called for an immediate ceasefire in Gaza.
