Qatar says Israel and Hamas have agreed to a two-day extension to the current truce, which has seen hostages freed and Palestinian prisoners released.
US national security spokesman John Kirby says Hamas has committed to releasing another 20 women and children over the next two days.
Families have been informed by the Israeli government that a further release of hostages will continue.
As part of the Israel-Hamas deal, 39 Israeli hostages in Gaza have been released so far, with 117 Palestinians freed from Israeli jails.
