New York has chosen its new mayor - Zohran Mamdani. He’s a Muslim, was born in Uganda, and loves Arsenal. He’s also pretty young. The politician has been making waves online with his social media campaign and united a huge Gen Z force behind him. From viral moments like jumping in the sea in a suit to walking the entire length of Manhattan, he’s probably appeared on your timeline.

So, what made his campaign go down so well with younger voters? We speak to BBC journalist Nathalia Jimenez, who has watched all this unfold in New York. She explains whether other politicians around the world can learn from his success.

We also hear from young New Yorkers and their experience taking part in some of the mayor-elect’s events, as well as Ugandans, who share what it’s like to see someone from their country go and win an American election.

The Amazon rainforest is home to billions of trees, animals and people. It’s spread across nine countries in South America - Brazil, Peru, Columbia, Bolivia, Ecuador, French Guiana, Guyana, Suriname and Venezuela - but the majority of it, almost 60%, is in Brazil. As well as being rich in biodiversity, the Amazon is also very important in the world's fight against climate change; as it absorbs carbon dioxide and produces oxygen.

But the Amazon has been declining. In fact, in 2022 Brazil set a new deforestation record for the amount of trees cut down in the rainforest in one month. This impact is being felt directly by the indigenous groups who have been living there for thousands of years, but also the world as a whole. In this episode we’re joined by Graihagh Jackson, from the BBC’s The Climate Question podcast, and Dr Erika Berenguer, who’s a Senior Research Associate at the University of Oxford and Lancaster. We chat about why the Amazon is so important, and what’s being done to protect it. This year’s climate summit Cop30 is being held in Belem, in the Amazon, for the first time. So we also discuss what impact this could have on the world’s largest rainforest.

The RSF (Rapid Support Forces) have taken the city of el-Fasher, in Darfur, from the Sudanese army. The city had been under siege by RSF fighters for 18 months, trapping hundreds of thousands of civilians and sparking a hunger crisis. Thousands are now trying to flee. And there are mounting fears of mass killings and sexual violence - some of which are feared to be ethically motivated.

The civil war in Sudan has been going on since 2023. But some believe that this could be a turning point. Deka Barrow, a journalist from BBC Monitoring who’s based in Nairobi, joins us to explain why. We also hear from someone who is trapped in el-Fasher.
