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.

Israeli officials will head to Qatar on Sunday for ceasefire talks with Hamas despite the “unacceptable” changes the terrorist group made to the U.S.-arranged Gaza ceasefire proposal, Prime Minister Benjamin Netanyahu‘s office announced.
