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.

Last minute negotiations between Hamas and Israel on a ceasefire deal delayed the release of hostages by a day.

Israel intensified strikes on Gaza hours after a ceasefire and hostage release deal was announced, residents and authorities in the Palestinian enclave said, and mediators sought to quell fighting ahead of the truce's start on Sunday.
