Crossing Continents

'I'll marry your sister if you marry mine. And if you divorce my sister, I'll divorce yours.' That is Yemen's 'Shegar', or swap marriage, an agreement between two men to marry each other's sisters, thereby removing the need for expensive dowry payments. But the agreement also states that if one marriage fails, the other couple must separate, too, even if they are happy. BBC Arabic's Mai Noman returns to her native Yemen and hears the stories of two women who have loved and lost because of Shegar. Nadia lives in the village of Sawan on the outskirts of the capital Sana'a with her family. She was married off at the age of twenty two and has three children. But because of her family's decision to marry her in the Shegar tradition she was forced to divorce when the other couple's marriage failed. Now she and her mother have to live with the stigma attached to divorce, and she only has limited access to her children, who remain with her ex-husband's family. Nora and her brother Waleed had little say in marrying their cousins through Shegar. But when one marriage failed, hard choices had to be made by everyone. Mai asks why an old tradition that forces you to love only to force you to part, is still practised in Yemen.Producer: Arlene Gregorius.

In one case, a patient called Annie, 38, was discovered in her crowded shared house in harrowing conditions. She was taken away to hospital but disappeared into the system.

Mobeen Azhar reports from Karachi, Pakistan's biggest city, where police are at war with the Taliban. Given rare access to the work of the police by a Senior Superintendent in Karachi's Criminal Investigation Department, Mobeen joins officers on a night time raid in search of the men who train suicide bombers. He meets a suspect in custody who brags about planting bombs and describes how he urges teenage boys to sacrifice their lives in violent jihad. Mobeen also talks to a businessman who was kidnapped for ransom and meets the families of police officers who have been killed by the militants. Assassinations linked to political parties have blighted the city for over a decade but today, more than 70 groups representing the militant Taliban are also fighting for control. This guerrilla war, once confined to the tribal belt of Waziristan has moved into Karachi with devastating results.

In one remote district in Ivory Coast, men are going back to school. Their studies are part of a UN-backed project dubbed 'the school for husbands' and designed to save the lives of women and children. The idea is to teach decision makers - the men - about the importance of family planning, check-ups, and pre-natal care for their wives. The aim is to help women and also improve general welfare in farming villages where food is scarce and incomes are dependent on the weather and good fortune. Lucy Ash hears stories from the schools for husbands and finds out why Ivory Coast's health system is struggling to recover from the post-election crisis three years ago, even as the country's economy roars ahead.Producer: Mike Wendling.

It has one of the largest fishing fleets in the world and much of the catch from Thailand's fishing boats ends up on Japanese, European and American plates. Yet the industry stands accused of profiting from slave labour.The BBC's Becky Palmstrom investigates this tale of modern day slavery. She travels to Thailand and Myanmar to find out why and how illegal migrants are being forced onto Thai fishing boats, many of them working for months unpaid. She hears allegations of cruelty and even murder.In Thailand Becky meets Ken, from rural Myanmar, who hoped to make a better life for himself and his ageing parents. He ended up being trafficked twice onto Thai fishing boats. The BBC team was able to bring his parents, back in Myanmar, the first news they had had of their son for four years.The Thai authorities admit that most of their fishing fleet is unregistered and much of it relies on illegal migrant labour. The Thai government insists it is making every effort to clamp down on trafficking and forced labour in its fishing industry. Yet the US State Department has recently downgraded Thailand to Tier 3 in its "Trafficking in Persons Report (TIP)" - a measure of how little it believes Thailand is doing to curb the problem.

In the Spanish mining town of Turon a male choir meets once a week for rehearsals. They often sing to the patron saint of miners Santa Bárbara Bendita. Since 1934 miners have been singing this beautiful song in memory of four miners killed in a mining accident in the Maria Luisa mine. Coal mining, once a major industry in Spain, has been in decline for years and in the next few years the EU's subsidies for non-profitable pits will stop altogether. For most miners the closure of pits signals the death of their communities. Natalio Cosoy travels to northern Spain to talk to the miners and their families. Will Santa Bárbara Bendita watch over them as they face an uncertain future? James Fletcher producing.

The last decade has seen a dramatic increase in cocaine trafficking through Guatemala en route north, to the United States. Part of the fallout locally, has been a rise in addiction. As a result, more than 200 drug rehabilitation centres have been set up in the capital alone. Many of these are run by Pentecostal churches, with little oversight or regulation. Often addicts are swept up from the streets by 'hunting parties', and forced to attend such a centre. Linda Pressly travels to Guatemala City to investigate compulsory drug rehabilitation.

Gaelic Football is Ireland's most popular sport - there are clubs in every parish of the country. The game is very much part of the Irish identity. But it is losing its lifeblood. And all because of emigration. John Murphy goes to the far west of Ireland, to learn about this uniquely Irish game and hear how clubs are struggling to keep going as more and more young people leave the country, to find jobs abroad. Helen Grady producing.

Almighty God vs the Red Dragon: It sounds like a fantasy action film but it is in fact a real and disturbing struggle in China. The most vivid case involves a group of people who beat a stranger to death in a fast food restaurant. They said they had no choice because the victim was a 'demon'. The killers are fanatical followers of the Church of the Almighty God, a Christian doomsday cult which claims millions of members across China and pledges to overthrow the Chinese Communist Party - which it calls the 'Great Red Dragon'. Gracie uses her fluent Chinese to gain access to families of those caught up in the cult, including a man who infiltrated it to save his wife.

Europe and the US have imposed the toughest sanctions on Russia since the Cold War amid anger over the Kremlin's support for east Ukrainian separatists who stand accused of shooting down a Malaysia Airlines passenger jet. But the crisis began further south with Russia's annexation of Crimea in March.Crimea's idyllic scenery drew Soviet visitors for years - some called it the Communist Cote d'Azur. The collapse of communism did little to dent Russia's appetite for their bit of paradise on the Black Sea along with the thousands of Ukrainian holidaymakers who flocked there each year. But now the Ukrainians are staying away and the Russian government is trying to fill the gap by urging employers in Russia to send staff on subsidised breaks in Crimea. A holiday in the newly annexed peninsula has become every Russian's patriotic duty. For Crossing Continents, Lucy Ash visits Crimean tourist resorts and explores the motives behind Vladimir Putin's fateful decision to reclaim Russia's paradise.
