The Israeli government has approved a ceasefire and hostage deal with Hamas, leading to a possible end to 15 months of a devastating war in Gaza that spread to other parts of the Middle East.
The deal was set to be ratified by the Israeli Cabinet on Thursday. But Netanyahu says, without specifying, that Hamas has gone back on several parts of the ceasefire deal at the last minute.
Israel and Hamas have reached an agreement on a multiphase ceasefire that commits them to end the war in Gaza, President Biden and Qatar's prime minister announced separately on Wednesday.
Negotiators in Qatar are close to a ceasefire deal that sees an exchange of Israeli hostages for Palestinian detainees, a six-week pause in fighting and eventual troop withdrawal from Gaza.
The basic framework, officials familiar with the talks say, is an exchange of Israeli hostages for Palestinian prisoners, and a six-week ceasefire. Mediators are applying pressure on all parties.
The president-elect made a similar pledge on social media in early December. His latest comments came during a wide-ranging news conference from Mar-a-Lago.
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.
Amnesty International says Israel has sought to deliberately destroy Palestinians in its war with Hamas, by mounting deadly attacks, demolishing vital infrastructure and preventing aid deliveries.
