Israel and Hamas reached a deal to resolve a disagreement over the exchange of a female civilian hostage that had threatened to derail the truce. Lebanon, however, saw the deadliest day since Israel’s truce with Hezbollah took effect.

Israeli troops fired on people trying to return home to southern Lebanon and delayed a return home for northern Gaza residents. Israel blamed Hezbollah and Hamas.

The hostages are the second set to be released since the multiphase agreement came into effect, raising hopes for a lasting end to the war.
