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.

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.

After intense negotiations, Israel and Hamas have reached a deal that would see a ceasefire and the exchange of hostages in Gaza for Palestinian prisoners.
