Israel says Hamas has not provided any information about the status of those 34 hostages, dampening any notion that the endorsement is a step toward a deal to stop the war.

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.

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.Late on Sunday, a senior Hamas official told AFP the group had "agreed to release 34 Israeli prisoners from a list presented by Israel as part of the first phase of a prisoner exchange deal".

A list of hostages that could be released in a ceasefire deal circulated in international and Israeli media on Monday amid reports that ceasefire negotiations were once more gaining momentum. But the Israeli government is warning that the list does not reflect any agreement — or information about the status of the people on it.

Israel and Hamas are once again struggling to reach a ceasefire that could wind down the 15-month war in Gaza and bring home dozens of Israelis held hostage.

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.

A senior Hamas official has shared with the BBC a list of 34 hostages that the Palestinian group says it is willing to release in the first stage of a potential ceasefire agreement with Israel. It is unclear how many hostages remain alive.
