Israel and Hamas signed a deal for a ceasefire set to begin Sunday January 19th that will see the exchange of Israeli hostages for Palestinian prisoners in Israel and the flow of humanitarian aid into Gaza. The news was met with celebrations in Gaza where Palestinians have been suffering under a brutal Israel offensive since the Hamas attack on October 7, 2023. Tens of thousands are dead, more than a million displaced and much of the strip is destroyed.

Chaim Levinson, senior diplomatic correspondent at Ha’aretz, joins us to parse through the details of the deal, how it was reached and what could happen next.
