Israel-Gaza updates: Hamas has received proposed hostage deal, Qatar says

The Israel Defense Forces said its soldiers are sending "large volumes of water" into Gaza tunnels to try to stop terrorist infrastructure.

"The pumping of water was only carried out in tunnel routes and locations that were suitable, matching the method of operation to each case," the IDF said in a statement. "This project was developed following combat procedures, accelerated force-building efforts, and while training forces with technological expertise."

"This tool represents a significant engineering and technological breakthrough in combating the threat of underground terror infrastructure and is the result of a collaborative effort between various bodies in Israel’s security establishment," the IDF added.

The latest proposed hostage deal includes an at least six-week pause in hostilities, during which the remaining civilian hostages in Gaza would be returned in phases, with the elderly, women and any remaining children released first, two U.S. officials confirmed to ABC News.

When the six-week truce nears the end, the framework calls for the parties to begin discussing: the return of all Israeli soldiers detained by Hamas; paving the way for all hostages in Gaza to be freed; and possibly extending the pause, the U.S. officials said.

The framework also includes the release of a large number of Palestinian prisoners held in Israel and additional humanitarian provisions for civilians in Gaza, the officials said.

According to an Israeli source, Israel has rejected this current hostage and cease-fire deal on the table.

Hamas leader Ismail Haniyeh said Tuesday the group is studying a proposal for a hostage and cease-fire deal that was put forward during talks this weekend in Paris. He said he would visit Egypt to discuss the plan and ways to implement it.

Qatar's Prime Minister and Minister of Foreign Affairs Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani said there is progress in the ongoing negotiations.

The White House is expressing confidence to secure the release of the remaining hostages being held by Hamas even after Israel rejected the current deal.

"The president's view is we got to continue to do everything we can to get those hostages out," National Security Council spokesperson John Kirby said Tuesday. "We are making progress on trying to get an extended pause in place so that we can get those hostages out. And the president's not going to wait on that."

Kirby would not say if President Joe Biden was disappointed that Israeli Prime Minister Benjamin Netanyahu said Israel would not release thousands of prisoners and pull troops out of Gaza as part of the deal.

"I think we’ll let the prime minister speak for himself. There's no reason for us to change course here. We still believe that this is the right thing to do," he said.

Kirby said national security adviser Jake Sullivan met with Amir Sheikh Al Thani of Qatar Tuesday to discuss the war and efforts to get a hostage deal in place. Sullivan is also meeting Tuesday with the families of hostages being held by Hamas.

Israel has rejected the current hostage and cease-fire deal that was on the table, an Israeli source told ABC News Tuesday.

The deal included the release of women, the elderly and the injured hostages. This is likely to be the terms of the first round of a future deal, the source said.

Israeli Prime Minister Benjamin Netanyahu said Tuesday, "I hear talk about all kinds of deals. I would like to make it clear: We will not conclude this war without achieving all of its goals. This means eliminating Hamas, returning all of our hostages and ensuring that Gaza never again constitutes a threat to Israel.”

Meanwhile, Hamas leader Ismail Haniyeh said Tuesday the group is studying a proposal for a hostage and cease-fire deal that was put forward during talks this weekend in Paris. He said he would visit Egypt to discuss the plan and ways to implement it.

Twenty aid organizations have joined together to express deep concern and outrage that some of the largest donors suspended funding for the United Nations Relief and Works Agency (UNRWA), the largest humanitarian agency in the Gaza Strip and the main provider for millions of Palestinians in the wider region.

A wave of countries, including the United States, have cut funding for UNRWA in recent days over Israel's accusations that 13 UNRWA staff members in Gaza were involved in the Oct. 7 terror attack. UNRWA said it is investigating the allegations.

In a joint statement released Monday, 20 non-governmental organizations, including Oxfam and Save the Children, urged the donor states to reverse their suspensions and warned that not doing so could lead to "a complete collapse of the already restricted humanitarian response in Gaza."

"We are shocked by the reckless decision to cut a lifeline for an entire population by some of the very countries that had called for aid in Gaza to be stepped up and for humanitarians to be protected while doing their job," the NGOs said. "This decision comes as the International Court of Justice ordered immediate and effective action to ensure the provision of humanitarian assistance to civilians in Gaza."

The NGOs warned: "If the funding suspensions are not reversed we may see a complete collapse of the already restricted humanitarian response in Gaza."

"The suspension of funding by donor states will impact life-saving assistance for over two million civilians, over half of whom are children, who rely on UNRWA aid in Gaza," they added. "The population faces starvation, looming famine and an outbreak of disease under Israel's continued indiscriminate bombardment and deliberate deprivation of aid in Gaza."
