Israeli Prime Minister Benjamin Netanyahu claims that Hamas has backtracked on a ceasefire agreement, which is awaiting approval from the Israeli government. Hamas is objecting to a clause that would give Israel the ability to veto the release of certain Palestinian prisoners. Netanyahu has instructed Israeli negotiators to stand firm on the earlier agreement. The ceasefire deal does not come into force until Sunday and will need to be approved by Netanyahu's security cabinet and government. The deal outlines a six-week initial ceasefire phase, including a gradual withdrawal of Israeli forces from central Gaza and the release of hostages by Hamas.
