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.

Cease-fire talks between Israel and Hamas stall amid hostage disputes, political tensions, and aid access issues.

The deal comes more than 20 months into the conflict -- and more than three months after a previous deal ended.
