Israel delayed a cabinet vote on the cease-fire deal in Gaza after Prime Minister Benjamin Netanyahu accused Hamas of reneging on parts of the agreement, underscoring the pact’s fragility as mediators worked to ensure the deal’s planned implementation on Sunday.

Israeli Prime Minister Benjamin Netanyahu 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.

The deal, scheduled to be implemented from Sunday, outlines a six-week initial ceasefire with the gradual withdrawal of Israeli forces from the Gaza Strip, where tens of thousands have been killed.
