The dispute underscores the fragility of the deal as mediators worked to ensure that it would go into effect on schedule.

Israeli Prime Minister Benjamin Netanyahu has accused Hamas of backing out of a cease-fire deal to release hostages and end the war in Gaza, which has raged for more than a year. An Israeli Cabinet vote on the cease-fire deal has been delayed indefinitely.

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.
