Former Israeli Prime Minister Ehud Olmert, in an interview with NDTV, stated bluntly, "Hamas will not release all the hostages, which is the only asset they still hold" unless it is guaranteed that the war is finished.

As Israel and Hamas move closer to a ceasefire agreement, Israel says it wants to maintain troops in a southern corridor of the Gaza Strip — a condition that could derail the talks.

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.
