Israel and Hamas are believed to have agreed that 10 living hostages and the remains of 18 others should be released during the first 60 days of a cease-fire, but they have not reached a consensus on how many Palestinian prisoners should be freed during the same period. Up to 20 hostages are still thought to be alive.

Hamas has warned that no Israeli hostages would be released without Israel making a "serious deal" with the group and that it will determine the terms. Newsweek has reached out to the Israeli Prime Minister's office and the U.

A US special envoy said a Gaza deal was close, and that a 60-day ceasefire and the return of 10 surviving hostages could be announced this week.
