What do the stolen love letters of John Keats have to do with homicide on the streets of New York?  Prosecuting both crimes falls under the remit of assistant district attorney Matthew Bogdanos.   A retired Marine colonel with both law and classics degrees, he has been the head of the Manhattan District Attorney's Antiquities Trafficking Unit since its creation in 2017. In his time on the job, the office has has seized more than six thousand pieces of stolen art and antiquities from various museums, art galleries and private homes in order to return them to their countries of origin. In this Crossing Continents, Sandra Kanthal travels to New York to learn more about this special unit of law enforcement and the reasons why one man thinks tracking down stolen treasures of the art world and reuniting them with their rightful owners is vitally important to our past and for our future.

The Victoria Falls on the border of Zambia and Zimbabwe is one of the natural wonders of the world. It's also one of Africa's great tourist attractions. As both countries seek to grow the tourism economy, there’s been a push to develop land around the Falls. But as Isa Jacobson reports from Zambia, it's led to fears for the preservation of the World Heritage Site, and warnings that the loss of land will exacerbate a deadly conflict between local people and wildlife.Presenter: Isa Jacobson Producer: Alex Last Sound Mix: Neil Churchill Production Co-ordinator: Gemma Ashman Series Editor: Penny Murphy

How amid the tents and the rubble Gaza is developing once again as an unlikely tech hub. Even before the October 7th 2023 attack and the subsequent war between Israel and Hamas, NGOs, with the backing of Google, had sought to develop tech start-ups in the Gaza strip. The digital economy was one of the few areas in which young Gazans in particular could seek to earn money for their families. During the two years of war they struggled for food and water. Forced to move from place to place, most of them lost their homes, their work, sometimes their laptops and plenty lost family members. Now 80% of Gazans are unemployed and have no income. Many of them live amid the rubble in tents. Stable electricity and internet are difficult to come by. And yet co-working hubs have begun to pop up, giving well educated graduates a chance to work remotely for foreign companies as coders, software engineers and app developers. With Israel controlling what comes in and out of Gaza, they still face significant obstacles, not least finding decent internet, electricity and spare parts for their laptops. And with near-daily bombings continuing, Gaza’s wider recovery remains uncertain. Yolande Knell reports on how its tech workers give a glimpse of a brighter, possible future, open to the world beyond Gaza’s borders.

In 2017, five men digging in an open pit found the third largest diamond ever unearthed in west Africa. It was dubbed the Peace Diamond, in memory of the brutal civil war that had ravaged large parts of the region in the 1990's – a war driven in part by factions competing for control of the diamond trade. When the Peace Diamond sold for $6.5 million at auction in New York, the government pledged some of the profits would provide solar power, a clinic, a school and a road connection for the Sierra Leonean village where it was found. Each of the diggers and the pit’s owner also got a small share of the spoils. Nine years on, we return to Sierra Leone to see how much the government kept their promise and to what extent the discovery really did transform the lives for those involved for better, or for worse.

Nadia Marcinko, originally Marcinková, was born in Slovakia and met Jeffrey Epstein as an 18-year-old model. Later, she became a successful aircraft pilot. For seven years, she was Epstein’s main girlfriend. And she’s one of four women that US prosecutors named in a 2008 plea deal as his “potential co-conspirators”. But she’s never been accused of any crime. And she’s described herself a victim who was abused physically and psychologically by Epstein. Now, a committee of the US Congress is beginning to address the sensitive question of whether it’s possible for someone to be both a victim and an accomplice, as it takes testimony from two of the “potential co-conspirators”, Epstein’s former assistants Sarah Kellen and Lesley Groff. Nadia Marcinko, who disappeared from public view several years ago, may also be called to testify. BBC reporter Tim Whewell and independent Slovak journalist Jakub Pohle have talked to people who’ve known her, and dug deep into the Epstein files, to put together the most detailed account yet of her life.

Since 2023, Sudan has been engulfed by a brutal civil war. More than 150,000 people have been killed and millions have been displaced. The war began as a power struggle between the Sudanese military and the powerful paramilitary group the Rapid Support Forces (RSF). The capital Khartoum was the epicentre of the conflict. Millions fled as fighting wrecked the city. In 2025, the Sudanese military finally retook the capital from the RSF. One year on, Mohanad Hashim returns home to Khartoum to see how life is slowly returning to the battered city.Reporter: Mohanad Hashim Producer: Alex Last Sound mix: Neil Churchill Production Co-ordinator: Katie Morrison Series Editor: Penny Murphy

Eighteen months ago, the renovation of the railway station in Serbia’s second biggest city, Novi Sad, led to a tragic accident. A substantial concrete canopy, which ran across the front of the station building, suddenly collapsed, killing sixteen people. The disaster sparked mass protests. Marchers demanded justice for the dead and injured. As the protests spread, to the capital, Belgrade, and to towns and cities across the country, the demands evolved. Protesters accused the government of corruption and of covering up the truth about what happened. The government accused the protesters of being foreign agents, supported and organised by malign outside forces. Now, after more than a year, the mass protests have finally subsided. Jill McGivering is in Serbia to find out what’s happened to that explosion of anti-government anger.

Is defence of the petrol car and liberated motoring becoming the new battleground for Europe’s populist parties? Chris Bowlby visits one of the homes of German car culture and a populist stronghold, Zwickau, to see how motoring is rising up the German agenda. Is Zwickau a foretaste of something affecting all of Germany – a car-loving, car-manufacturing powerhouse in the past, now wondering anxiously what the future holds against the emergence of Chinese electric cars. And less than a hundred miles from Zwickau, just across the border in the Czech Republic, a new coalition government has recently taken power, including ministers from a populist party called Motorists for Themselves – muscular defenders of the old petrol car.

Iceland is an island of great beauty and even greater strategic importance. Its position in the Greenland Iceland UK Gap, the gateway between the Arctic and Atlantic oceans, makes it crucial to Nato operations in the High North. But Iceland is one of the few nations in the world with no military of its own. A country of approximately 400,000 people, its security relies on the umbrella of protection it derives from being a founding member of NATO, a bilateral agreement with the United States signed in 1951 and a highly skilled coast guard and police force. In a climate of fracturing political alliances, is entrusting national defence so heavily on the guarantees of allies a sustainable strategy? Sandra Kanthal travelled to Reykjavik to find out.

Outbreaks of HIV have become regular occurrences in Pakistan. And too frequently it is the children who suffer. In the city of Taunsa, for example, children have tested positive for HIV while their parents have not. So what’s been going on? In Crossing Continents Ghazal Abbasi investigates what and who is to blame. With the help of a staff insider and undercover recording in the city’s main hospital, the BBC finds shocking lapses in medical protocol. Medicine vials and syringes are often re-used for different children. Cross-contamination seems inevitable. But the local authorities deny the hospital is at the centre of the problem.
