The office of Israeli Prime Minister Benjamin Netanyahu said that it had approved a list of Palestinian prisoners to be released, should more Israeli hostages also be freed.
"The government has approved the inclusion of 50 female prisoners in the list of prisoners eligible to be released in the event that a release of additional Israeli hostages is carried out," Netanyahu's office said in a post on social media platform X, formerly Twitter.
Under the terms of the initial agreement, 50 Israeli hostages taken by the militant-Islamist Hamas group would be released in return for 150 Palestinian prisoners.
Mediator Qatar on Monday announced that the temporary pause in fighting in Gaza had been extended by two days, although there has been no official confirmation from Israel.
Israel has said the truce could be extended by an extra day for every additional 10 hostages freed, but has vowed to quickly resume its offensive once it ends.
