The Israeli occupation's Prison Service confirmed receiving a list of Palestinian detainees requested in the next release, adding that they will be moved to Ofer Prison in the occupied West Bank for medical checks by the International Red Cross, ahead of their release to the West Bank or East Jerusalem.

Israel's Channel 13 reported that the list includes 39 Palestinians, out of the 8,000 Palestinians in Israeli jails.

Earlier, the office of Israeli Prime Minister Benjamin Netanyahu said it had received a list of the Israeli detainees in Gaza. 

There is no official announcement on the number to be released, but the Ynet news site and Army Radio say that Israeli officials confirmed they expect 13 Israelis to be released. 

US National Security Adviser Jake Sullivan says there is “reason to believe” an American citizen will be released from Gaza today.

“We have reason to believe one of those Americans will be released today, but until we see her out safely from Gaza, in the hands of the authorities and ultimately in the hands of her family, then we won’t be certain,” Sullivan tells NBC.

As part of the truce deal, Hamas is expected to release a total of 50 Israeli children and women in exchange for 150 Palestinian children and women.

There are three Americans in the eligible category — two women, and a four-year-old girl.

Hamas has already released 26 Israelis in exchange for 78 Palestinian detainees in the two releases already completed.

The resistance group has also released 14 Thais and one Filipino.

Meanwhile, the International Committee of the Red Cross refuted earlier comments by its official Pascal Hundt to Sky News that he was “not confident” more captives would be released today.

“An earlier statement from an ICRC official was in no way an indication that the release operations planned for Sunday will not happen. All preparations for the next release continue to move forward”, the ICRC stated.

Speaking from Gaza, Hundt told Sky News that he is "hopeful" but "not confident" that a third round of captive releases from both sides will go ahead today. 

 "I don't know if we will see it, but I really do hope that everything goes without any problems as we saw during the last two operations," he said.
