According to the Guinness Book of World Records, TB is humanity’s oldest contagious disease. It has become something of an afterthought in rich nations, but remains the world’s most deadly infectious disease. In 2024 it killed more than 1.2 million people.

South Africa has one of the highest TB burdens in the world, but it has also developed one of the most sophisticated scientific ecosystems for the study of the disease. Clinical trials conducted in the country have been crucial to the innovation of TB treatments, vaccines, diagnostics and prevention strategies.

Much of the funding for this research comes from American institutions. But since early 2025, streams of that money have been withdrawn due to a series of decisions by the Trump administration.

For Crossing Continents, Sandra Kanthal visits Cape Town and discovers the story of two intertwined landscapes: the people in local communities struggling with the burden of tuberculosis, and the scientific institutions embedded in them trying to tackle the disease - and why at the moment both are struggling.

People in Gainesboro, Tennessee, have some new neighbours. A conservative developer has bought land just outside the tiny rural Appalachian town, with the aim of forging an 'aligned' community based on shared values like 'faith, family and freedom'. Two of the first people to come to town are controversial Christian nationalists who talk about civilisational collapse and the 'imperative for like-minded Christians to gather and fight'.

Their extreme views on women, civil rights and the role of the Church have attracted the attention of critics both locally and further afield. In Gainesboro itself, a resistance movement has formed, and the battle lines have been drawn.

This small town of 900 people has become a symbol of the next frontier of America’s political warfare. Is the new development a haven for hate and extremism, with the newcomers looking to take over local power? Or are they just conservative businessmen catering to a renewed demand for the rural, traditional lifestyle? What actually is Christian nationalism? And what is it like for the locals, whose little town has been thrust into the spotlight? Ellie House reports from Gainesboro, Tennessee.

After decades of extinction, wild jaguars are once again roaming in Northern Argentina. It has been at least thirty five years since a wild jaguar cub was spotted in this dry and dusty part of Argentina. But in August 2025, a baby appeared on the chocolatey-brown banks of the River Bermejo. Its existence was a great success for the team from Rewilding Argentina, a non-profit foundation that started reintroducing these magnificent beasts here in 2019. But it has not been easy: hunting is still a problem and the organisation has had to get the locals on board with sharing their home with big cats. For Crossing Continents, Charlotte Pritchard travels to 'The Impenetrable Forest' to find out how the birth of this baby became possible.

In plain sight, in a modern city, a colleague offers to drive you home after work. How would you respond? One woman in Kazakhstan accepted the lift only to find herself kidnapped or ‘stolen’ as a bride. She got away, rescued by the police, but for many Kazakh women kidnap leads to marriage.

Human Rights lawyer Khalida Azhigulova reckons that thousands of women are forced into marriage each year in Kazakhstan, including many who are abducted. Some women even find that a wedding has already been arranged by the time a kidnapper gets her home. Now, after 20 years of campaigning by Khalida and other activists, legislators have passed a law making forced marriage a crime.

Monica Whitlock and Roza Kudabayeva travel to Kazakhstan to meet women who’ve been kidnapped, and hearing about the intense pressures that make them feel obliged to marry their abductors. Women like Gulbala who endured 20 years of marriage with her kidnapper and is now making a new life for herself. And Klara who is crystal clear that it’s time for a change. All her children will marry in the proper way, she says, because no one should be forced into marriage.

Bride stealing is a problem not only in Kazakhstan, but in many other parts of Central Asia and the Caucasus. It’s often defended as ‘tradition’ rooted in the Kazakh’s nomadic past. Nonsense, says Khalida. ‘Kazakh girls in the nomadic community were raised as warriors. They were taught to ride a horse, how to gallop, how to use arms and how to fight. She would not let anyone kidnap her'.

Two years ago a group of Jewish and Palestinian peace activists stood almost alone in Israel in calling for a ceasefire, as Israel launched a massive offensive on Gaza in response to the Hamas attacks of 7th October 2023. Emily Wither returns to hear how the lives of these activists have changed. She explores whether their message of peace and coexistence is breaking through at a time when societal divisions are deeper than ever.

The group Standing Together, known for their matching purple t-shirts, is a group of Jewish Israelis and Palestinian citizens of Israel (referred to by the state as Israeli Arabs, the country’s largest minority making up over 20% of the population).

It is unusual in either Israel or Palestine to find a mixed group working together for a shared cause and advocating for coexistence. Standing Together has received criticism from both sides of the conflict; with many Israelis calling them traitors and some Palestinian groups calling for a boycott of the movement. Despite all this the group say the only way to achieve a lasting peace is for the communities to work together.

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.

How Haitians in the Dominican Republic are being targeted for expulsion.

Much of the construction work building those tourist facilities is in fact done by Haitians, and many of the staff who work in them are from Haiti, which occupies the western half of this island of Hispaniola. Over recent years the tourism industry has helped make the Dominican economy the fastest growing in Latin America.

However, the Dominican government is now implementing one of the most systematic deportation policies anywhere in the world. Last year the president, Luis Abinader, announced that his country would expel illegal migrants at the rate of ten thousand a week. The chief target is Haitians and people of Haitian descent. President Abinader says he is keeping his country secure and implementing the constitution. Meanwhile Haitians in the Dominican Republic are living in fear of raids by the immigration authorities and of being sent back across the border, to a country riven by violence as well as political and economic instability.

John Murphy is in the Dominican Republic to talk to Haitians stuck between a rock and a hard place.

Over the past year, Kenya has been rocked by anti-government protests. What started as a demonstration over proposed tax increases soon turned into a nationwide, youth-led protest over the state of the economy, alleged political corruption and police brutality. But it's come at a cost. Dozens of protestors have been killed in clashes with the police, and human rights groups say many activists have been abducted and tortured by agents of the states. Michael Kaloki meets the young Kenyans who are caught in a battle for change.

The history of Gaza dates back more than 5000 years. In antiquity, it was a key port on the Mediterranean coast. Assyrians, Ancient Greeks, Romans, Byzantines and the Ottomans have all left their mark on this small territory. This rich history is seen by Palestinians as central to their identity. Amid the death and destruction of the war, the BBC’s Middle East Correspondent Yolande Knell meets the Palestinians who’ve desperately tried to save what remains of Gaza’s past.
