We’re bringing you an extra episode of What in the World.

Israeli troops have killed Hamas leader Yahya Sinwar in Gaza. He is described as the mastermind of the 7th October 2023 attacks and Israel’s most wanted man.

We explain who Yahya Sinwar was and how he was killed and what the Israelis have said about him. Shaina Oppenheimer from BBC Monitoring goes through some of the reaction to his death, including from Palestinians and Arab social media.

And with the help of the BBC’s International Editor, Jeremy Bowen, we get answers to the big questions like what does this mean for the hostages taken on 7th October and the possibility of a ceasefire? Does this mean the war in Gaza will come to an end? And what will happen to Hamas, which is designated as a terrorist organisation by the US, UK and European Union?
