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.

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.

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.

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.

Albania has had many different faces over the last hundred years. Once ruled by the Ottomans, it became a kingdom before turning into a totalitarian communist state after the Second World War. During this time, no one was allowed in or out; all private property became state-owned, and bunkers sprang up across the country. After the fall of the communist regime, Albania descended into chaos. In 1996, a pyramid scheme that three quarters of the population had paid into, collapsed. People lost everything, and the country, especially the south, erupted into violence.

These days, Albania is aiming to shake off its past and transform its reputation from a country marked by corruption to one known for luxury tourism. With its miles of unspoilt beaches, snow capped mountains, and olive groves that could rival anything Greece has to offer, it’s unsurprising that it’s quickly attracting investors. Among them are Ivanka Trump and her husband, Jared Kushner, who are hoping to build a resort on an island off the coast of Vlorë. They have visited the secluded beaches of Zvërnec and Nartë; currently home only to endangered monk seals, sea turtles, and a few sheep. They, like others, hope to benefit from new government incentives to build luxury 5 star plus resorts.

However, ghosts of Albania’s communist past remain. Land disputes, allegations of corruption, and a lack of infrastructure could derail these resorts before they’ve even broken ground. For Crossing Continents, Emily Wither travels to Albania to find out whether it will be able to re-brand itself, and whether its dream of luxury escapism will become a reality.
