A four-day truce between Israel and Hamas will begin on Friday morning, with civilian hostages and Palestinian prisoners to be released later in the afternoon, Qatar announced Thursday, hours after the deal was originally meant to take effect.

The pause in fighting will start at 7 a.m. local time (midnight ET), with 13 women and children hostages to be freed at 4 p.m., according to a spokesperson for Qatar’s foreign ministry, Majed Al-Ansari.

The list of hostages who are expected to be released has been handed to the Israeli intelligence service Mossad, Al-Ansari said.

The Mossad will also hand over a list of Palestinian prisoners expected to be released to the Qataris, he added. “Whenever we have both lists confirmed this is when we can begin with the process of getting people out,” the spokesperson said.

An Israeli official told CNN a total of 39 Palestinian prisoners will be released Friday as part of the deal between Israel and Hamas.
