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

Qatari and Hamas officials say a last-minute dispute in cease-fire talks between Israel and Hamas has been resolved.

The deal, mediated by the United States, offered a glimmer of hope in a conflict that has taken an immense human toll.
