US National Security Council spokesman John Kirby says Israel commits to announcing each window at least three hours in advance.
Israel will begin four-hour pauses in northern Gaza to allow people to flee hostilities, the White House has announced, in what it called a step in the right direction.
US National Security Council spokesman John Kirby said the first humanitarian pause would be announced on Thursday, adding that Israel had committed to announcing each four-hour window at least three hours in advance.
President Joe Biden had asked Israeli Prime Minister Benjamin Netanyahu to institute the daily pauses during a call on Monday.
The Biden administration says it has secured a second pathway for civilians to flee the fighting between Israeli forces and Hamas.
More details soon.
