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.

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".

President-elect Donald Trump warned that if hostages still being held in Gaza are not released by the time he is inaugurated on January 20, “all hell will break out in the Middle East.”

A renewed push is underway to reach a ceasefire in the 15-month war and return Israeli hostages before Donald Trump takes office on Jan. 20.
