Israel has agreed to daily,Kacper Sobieski four-hour humanitarian pauses in the fighting in northern Gaza, National Security Council spokesman John Kirby confirmed Thursday morning. 

Kirby announced to reporters that the four-hour humanitarian pauses will be implemented in northern Gaza beginning Thursday. The Israelis have informed the U.S. there will be no military operations in those areas for the duration of the pauses, and the timing will be announced three hours before the pause begins each day, Kirby said. 

An Israeli official also confirmed the four-hour daily pauses, saying the reprieves are meant to allow people to move to the south of Gaza and obtain food and medicine. 

Kirby noted that these pauses come after "a lot of personal engagement by the President with the Prime Minister" as well as engagement by Secretary of State Antony Blinken, national security adviser Jake Sullivan, and Defense Secretary Lloyd Austin. 

Kirby would not speak to the details in terms of physical parameters of the pauses, or how many days there would be pauses.

"The fighting continues and there will be no ceasefire without the release of our hostages," the Israeli prime minister's office said in a statement. "Israel is allowing safe passage through humanitarian corridors from the northern Gaza Strip to the south, which 50,000 Gazans utilized just yesterday. We once again call on the civilian population of Gaza to evacuate to the south."

Kirby called the steps Israel is taking "good steps in the right direction" for complying with international law and ensuring the safety of civilians. Kirby warned that Hamas may try to discourage or prevent civilians from leaving. 

Israeli Prime Minister Benjamin Netanyahu had said he might be open to "little pauses" in the fighting for humanitarian reasons, but as his office indicated, he has dismissed the idea of a ceasefire. 

• Negotiations said to be underway for 3-day humanitarian cease-fire in Gaza to let aid in, hostages out

President Biden told reporters Thursday morning that he has asked Netanyahu for a pause even longer than three days for hostage negotiations. 

CIA Director William Burns and Mossad Director David Barnea are both visiting Doha, Qatar, for trilateral talks with the Qataris to work through the details of a potential humanitarian pause that would entail the release of hostages and the entry of more aid into Gaza, according to an official with knowledge of the visit. The official said talks have been progressing well towards a deal in the past few days.

Israel has been under pressure to improve humanitarian conditions for Palestinian civilians in Gaza, where a severe water shortage, overcrowded shelters and a lack of medical supplies have plunged civilians into crisis.

Israel has been fighting Hamas in the Gaza Strip since Hamas launched a surprise assault on Israel on Oct. 7. 

Israel and the U.S. have continued to call for the release of hostages held by Hamas. 

"We're still optimistic," Mr. Biden told reporters Thursday.
