Israel's cabinet is delaying ratification of a ceasefire agreement with Hamas due to last-minute demands from the militant group. Israeli Prime Minister Benjamin Netanyahu signaled the agreement is in jeopardy, saying his cabinet won't meet to consider the deal until Hamas backs down from what he calls last-minute demands.Netanyahu claims Hamas is objecting to part of the agreement that gives Israel final say over which Palestinian prisoners they release. Mediators from the U.S., Egypt, and Qatar are meeting today to try to finalize the deal.On Wednesday evening, President Joe Biden spoke about the details of the three-phased agreement he proposed last spring, adding members of the Biden and incoming Trump administration worked together with international mediators."We've been speaking as one team," Biden said. "This has been a time of real turmoil in the Middle East but as I prepare to leave office, our friends are strong, our enemies are weak and these are genuine opportunities for a new future."The agreement includes the release of dozens of Israeli hostages and hundreds of Palestinian prisoners, allowing hundreds of thousands of displaced people in Gaza to return home, and permitting badly needed humanitarian aid to enter the region.It's unclear how many hostages in Gaza are still alive. A senior Biden administration official says two Americans, Sagui Dekel-Chen and Keith Segel, were expected to be among those freed in the first group from Gaza. Another American, Edan Alexander, who also served as an Israeli soldier, is also being held. Alexander is expected to be released at a later date in the second phase of the agreement, if it goes through.Biden acknowledged that the ceasefire can only stay in place as long as Israel and Hamas remain at the negotiating table.New Israeli airstrikes in Gaza on Thursday killed at least 72 people, jeopardizing the agreement from taking effect on Sunday.
