Humanitarian aid to Gaza dropped by 50% from January to February, according to Philippe Lazzarini, commissioner-general of the United Nations Relief and Works Agency for Palestine Refugees in the Near East.

"Aid was supposed to increase not decrease to address the huge needs of 2 million Palestinians in desperate living conditions," Lazzarini said on social media Monday. "Among the obstacles: lack of political will, regular closing of the crossing points & lack of security due to military operations + collapse of civil order."

Lazzarini stressed the need for a cease-fire.

The Israel Defense Forces has presented Israel's war cabinet with a "plan for evacuating the population from the areas of fighting in the Gaza Strip," a release from the prime minister's office said early Monday local time.

"In addition, the plan for providing humanitarian assistance to the Gaza Strip in a manner that will prevent the looting that has occurred in the northern Strip and other areas was approved," the statement added.

Editor's Note: This post has been updated to reflect that the IDF presented the plan, not the prime minister's office, as originally reported.

Israel has agreed to an updated framework that would establish a six-week cease-fire in Gaza in exchange for the release of 40 hostages, an Israeli source told ABC News. The development follows talks in Paris, which includes officials from the U.S., Israel, Qatar and Egypt.

While Israel says it's waiting to hear back from Hamas on whether it will accept the updated language from this weekend's talks, Israel is pushing forward with plans to enter Rafah. Israeli Prime Minister Benjamin Netanyahu posted on X that operational plans and evacuation plans in Rafah are ready to be approved by his cabinet.

As part of the proposed deal, Israel has agreed to release jailed Palestinians at a higher ratio than the previous deal, which was 3 to 1. Up to 400 Palestinian prisoners could be released in this new deal.

The Israel Defense Forces will redeploy but not withdraw from Gaza.

Secretary of State Antony Blinken is signaling a possible shift back to a long-standing U.S. policy rejecting Israeli settlement expansion in the West Bank, calling it "inconsistent with international law."

Asked at a press availability in Argentina for his response to Israel’s purported plans to build thousands of new settlement homes in the area, Blinken responded, "We’ve seen the reports, and I have to say we’re disappointed in the announcement."

"It's been long-standing U.S. policy under Republican and Democratic administration alike that new settlements are counterproductive to reaching an enduring peace. They're also inconsistent with international law," Blinken said. "Our administration maintains firm opposition to settlement expansion, and in our judgment, this only weakens -- doesn't strengthen -- Israel security."

The Biden administration has condemned Israeli expansion in the West Bank for years, but the State Department had not yet gone so far as to say they ran afoul of international law after Blinken’s predecessor, Mike Pompeo, said in 2019 that the U.S. would no longer view Israeli settlements in the West Bank, Golan Heights and East Jerusalem as violations.

But before delivering his rebuke, Blinken made note of what he called a "horrific terrorist attack" on a Jewish settlement in the West Bank this week and said the U.S. would continue to support Israel’s right to defend itself and its people.

Hours after the U.S. Department of Defense conducted its first combined humanitarian assistance airdrop in Gaza with the Royal Jordanian Air Force, senior administration officials asserted this would be part of a sustained effort to scale up life-saving aid into Gaza and confirmed significant progress on a six-week hostage ceasefire deal currently in the hands of Hamas.

Senior administration officials said they are exploring every channel possible to get assistance into Gaza and that the Department of Defense is currently planning additional drops. However, they say their biggest obstacle is opening more avenues to get aid into Gaza, including a martine route that would deliver assistance directly by sea.

"We're looking at the land routes, we're looking at the sea route, we're looking at the air route, to really ensure that we're exploring every opportunity to get assistance in," officials said Saturday.

Officials confirmed this was the first U.S. airdrop conducted in Gaza since the war began and that U.S. and Jordanian C-130 aircraft were operated jointly out of Jordan to distribute aid.

Administration officials suggested the removal of police from the U.N. and other humanitarian convoys has exacerbated the lawlessness already prevalent in the region as gangs allegedly take and resell aid. Officials said the way to address this problem is by flooding the market with aid to discourage the commercialization of assistance.

Officials said a ceasefire is essential for the distribution of life-saving aid throughout Gaza. A deal is on the table and in the hands of Hamas, according to officials.

Senior administration officials told reporters there would be a six-week ceasefire as soon as today if Hamas agreed to release a defined category of vulnerable hostages, which include the sick, elderly, and women.

When asked about the specifics of these progressions towards a ceasefire hostage deal, admin officials said they'd worked hard with the Israelis to develop a framework which the admin believes is now "in the zone of a compromise amongst all the positions that had been on the table," after several meeting in Israel last week.

Admin officials hope to have this deal in place by Ramadan, confirming significant progress has been made over the last few weeks.

"The onus right now is on Hamas, their talks still underway," a senior admin official said Saturday.

They continued, "There has been significant progress over the last few weeks. But like all things, until the deal is actually done, It's not done. The Israelis have basically signed on to the elements of the arrangement. And right now, the ball is in the court of Hamas, and we are continuing to push this as hard as we possibly can."
