In a cinema in south-west Germany an audience is gathered to watch an Oscar winning film, Zone of Interest, about the life of Rudolf Höss, Commandant of Auschwitz. Those present comprise Jewish people from around the world, and the special guest is Rudolf’s grandson. The topic was rarely visited during Kai's childhood. It was only after a school history lesson that Kai began to comprehend Rudolf’s role as head of the largest mass murder site in history.

After years of Chinese investment in Africa, the West is fighting back. Through the Lobito Corridor project, the US and European countries are investing billions in Angola’s Benguela Railway, which runs from southern Africa’s interior to Angola’s Atlantic coast. The aim is to build a quick and reliable supply chain to export African minerals to the West. These minerals power the chips in all our gadgets, so they are pivotal in the US’s tussle with China. Plus, the project promises huge economic gains for Angola. Marcia Veiga takes the train to find out if ordinary Angolans will benefit, or if it is another case of foreign powers extracting African resources for their own gain.

In July 2024, Bolivia discovered the Mayaya Centro-X1 gas field, its largest find in nearly 20 years. With an estimated 1.7 trillion cubic feet of reserves, the announcement sparked excitement across the country, promising to help reverse a steep decline in domestic production and inject billions into the national economy. South American based journalist Constance Malleret explores what this discovery means for Bolivia - not just beneath the ground, but above it. We hear from geologists working at the site, government officials spearheading the Upstream Reactivation Plan, and energy analysts questioning whether the country is leaning too heavily on fossil fuel optimism.

Ranches, rodeos and public land. This is the story of a surprising battle raging in the American West, and the unlikely coalition it’s forged.

This episode of The Documentary comes to you from Assignment, investigations and journeys into the heart of global events.

Kurdish designer Lara Dizeyee is preparing a couture collection for Milan Fashion Week. Dizeyee fled Iraqi Kurdistan as a child, grew up in the US, and later returned to Erbil. Her designs draw on traditional Kurdish dress - layered garments, capes, and ornate headpieces - reimagined as bold evening wear. Her work is celebrated in Kurdistan, across the diaspora, and in the Arabian Gulf. Yet despite her growing profile, she lacked the funds to stage a show on the scale Milan demands. Arts journalist Melissa Gronlund follows her as she secures backing and races against time to source fabrics, sketch and sew designs, and collaborate with Kurdish artisans on jewellery and bespoke accessories. More than 30 outfits are completed and packed into suitcases carried by her extended family. On the big day, Dizeyee fits each model and navigates last-minute crises - models too short, earrings that won’t fit, designs that misfire. But as the models walk out in her reimagined Kurdish looks, the emotion in the room is unmistakable. And in that final moment, as the Kurdish flag is symbolically recreated on the runway, Dizeyee presents her culture to the world.

Blood spilled in Sudan's el-Fasher massacre is visible from space. What led to the latest dark turn of events that took place after the Rapid Support Forces seized the city in Northern Darfur from the Sudanese Armed Forces?

In this episode, first recorded in 2024, the Global Jigsaw digs into the prehistory of Sudan’s civil war. We focus on the power struggle between two men: Hemedti, in charge of the RAF, and Burkhan, the general leading the SAF. We ask who are the foreign powers aiding them, and why.

Networks of bots - automated social media accounts - have been found to be targeting European elections including, in the last year, those in Moldova, Poland and Germany. But could their real intention be to tie up news organisations with fact-checking? Damien Sharkov from BBC Monitoring has been looking at how they operate.

Earlier this year, news reports circulated online that a Vietnamese-American scientist called Anh Duong had a hand in creating the bombs used by America in its June airstrikes on Iran. Those reports turned out to be untrue, but Thuong Le from BBC Vietnamese has the real story of the chemical engineer known as 'the Bomb Lady.'

Something unusual happened recently at the Miss USA beauty contest: Miss Nevada, 22-year-old Mary Sickler, walked on stage without any hair. She had lost it to a condition known as alopecia but, until that moment, had worn a wig in public. Tens of millions of women around the world suffer from some form of hair loss and the story has sparked a global conversation. We bring together three women with alopecia, in the US, South Africa and the Netherlands. Many people having cancer treatment can also lose their hair – it’s usually temporary but can be permanent. Three women whose hair fell out during cancer treatment share their experiences of baldness, wigs and dating mishaps.

How Jihadists wrestle with the question: to use or not to use. The allure of this powerful tool and the damage they fear it could inflict on their image and reputation. Supporters of the Islamic State group tend to be early adopters of new tech, and some have already experimented with generative Artificial Intelligence. But that has exposed deep divisions in jihadist circles. The Global Jigsaw explores this debate to understand what “responsible AI” means for them.
