Hamas fighters were set to release a new wave of hostages Saturday in exchange for Palestinian prisoners, officials said, offering hope to anguished families after seven weeks of war that have killed thousands of people.

Key mediator Qatar was expected to announce the numbers of prisoners and hostages to be freed later Saturday, the second swap since a four-day cease-fire came into effect on Friday and largely silenced the guns on both sides.

Israeli authorities said they had received a list of the hostages to be freed but did not provide numbers or the precise timing.
