Israeli Prime Minister Benjamin Netanyahu’s office alleged that Hamas had backed out on parts of a Gaza ceasefire and hostage deal agreed Wednesday, potentially delaying a truce between the two sides that was set to go into effect on Sunday—a day before President-elect Donald Trump takes office.

Israel and Hamas have agreed a Gaza ceasefire and hostage deal following meetings with Qatar's prime minister, a source briefed on the talks has told the BBC. There was no confirmation from the Israeli government or Hamas, but a Hamas official earlier told the BBC it had approved a draft from Qatari, US and Egyptian mediators.
