Hamas has named 34 hostages, some of them believed to have died in captivity, who it says it would return to Israel in the first phase of an evolving if still elusive ceasefire in Gaza.

Israel said Monday that Hamas had not yet provided the status of 34 hostages the group declared it was ready to release in the first phase of a potential exchange deal.

The deal would secure release of a third of the approximately 100 hostages who remain in Gaza, including two dual U.S.-Israeli nationals. In return, Israel would release some Palestinian prisoners.
