A U.S. official told ABC News the hostage deal would involve Hamas releasing 50 women and children in exchange for a pause in fighting that would last four or five days. The deal would also involve the release of three Palestinian prisoners for each Israeli hostage, the official said.

The Palestinian prisoners are not considered hostages. Some of them were imprisoned prior to the conflict.

The official cautioned that the deal is not done. President Joe Biden has been personally involved in the negotiations, urging the emir of Qatar to press Hamas to accept the deal and urging Israeli Prime Minister Benjamin Netanyahu to accept the deal, according to the official.

President Joe Biden said Tuesday that "we're now very close" on a deal to release the hostages being held by Hamas, but the president did not discuss more details.

"We could bring some of the hostages home very soon, but I don't want to get into the details of things because nothing is done until it's done. And when we have more to say we will, but things are looking good," Biden said.

The World Health Organization said Tuesday that at least three hospitals in the war-torn Gaza Strip have requested help with evacuating patients.

Speaking at a press briefing in Geneva, WHO spokesperson Christian Lindmeier said planning was underway to evacuate Al-Shifa Hospital, Indonesian Hospital and Al-Ahli Hospital in northern Gaza, but that such an event was a last resort.

"It's robbing the entire population of the north of the means to seek health [care]," Lindmeier told reporters.

Two journalists were killed by Israeli bombing near the Lebanon-Israel border on Tuesday, according to Al-Mayadeen, the Beirut-based television channel they worked for.

Al-Mayadeen confirmed that reporter Farah Omar and photojournalist Rabie Al-Maamari were both killed near the southern Lebanese town of Tir-Harfa, about a mile from the Israeli frontier.

"The occupation targeted the Al-Mayadeen team directly and definitely intentionally," the channel said in a statement on Tuesday. "I tell the Israeli enemy that you will not be able to silence the voices of Al-Mayadeen. We will remain and continue our coverage and our honorable journalistic work, whose priority is covering the crimes of the occupation in Gaza, the West Bank, Palestine and Lebanon."

The Lebanese National News Agency reported that a civilian -- an 80-year-old woman -- was also killed by an Israeli airstrike in the southern Lebanese village of Kafr Kila, about 35 miles northwest of Tir-Harfa.

Lebanese militant group Hezbollah, which has voiced support for Palestinians in the besieged Gaza Strip and has been clashing with Israeli forces along the Lebanon-Israel border in recent weeks, released a statement on Tuesday "strongly condemning" the deaths.

"This aggression and the accompanying martyrdom of other citizens will not pass without a response from the fighters of the Islamic Resistance who are fighting in the field," the group added.

Hezbollah later issued another statement saying it had retaliated with a missile attack on Israeli troops near the border. The Israel Defense Forces confirmed in a separate statement that a number of rocket launches were identified from Lebanon toward Israeli territory in recent hours.
