Crossing Continents

Can you learn to code if you've spent your life studying religious texts? Can you be part of the fast-paced, secular world of technology and startups if you're from a conservative religious community? Israel has been called the "Startup Nation", with a flourishing technology sector playing a big role in the country's economy. But one group who haven't traditionally been involved are ultra-Orthodox Jews, known as Haredim. They often live apart from mainstream Israeli society and adhere to strict religious laws covering everything from diet to dress and technology. Many men don't work or serve in the army, spending their lives studying the Torah, subsidised by the government. It's a way of life that leaves many Haredim in poverty, and other Israelis resenting picking up the tab. But in recent years, the ultra-orthodox have been increasingly joining the high-tech world, working in big international tech companies and founding their own startups. David Baker travels to Israel to meet the new breed of high tech Haredim, and find out how they reconcile taking part in the "Startup Nation" with traditional Torah life.Produced by James Fletcher.

The United States is in the throes of a heroin and opiate epidemic. For Crossing Continents, India Rakusen travels to Lorain County, in the state of Ohio, where addiction has become part of everyday life. West of the city of Cleveland, Avon Lake is a wealthy suburb - its large, expensive properties back onto the shores of Lake Eerie, and wild deer frolic on neat lawns. But behind this façade, there is a crisis. Many families have felt the damaging impact of addiction. And across Lorain County, opiates - pharmaceutical and street heroin - have killed twice as many people in the first six months of 2016 alone, as died in the whole of 2015.Producer Linda Pressly.

After the last elections in Russia, mass protests against vote-rigging led to clashes in the centre of Moscow. The events on Bolotnaya Square were the biggest challenge President Putin has ever faced to his rule. Four years on, several demonstrators are still serving long prison sentences, the laws on protesting have been tightened and the arrests continue. As Russia gears up for parliamentary elections in September, Sarah Rainsford talks to some of those caught up in the Bolotnaya protests, and asks what their stories tell us about Putin's Russia today.

In the Colombian capital of Bogota, Lucy Ash meets two people who fear they will never be able to return to their homes. They both come from Choco, which is one of the poorest provinces and most violent parts of the country. Maria, an Afro-Colombian mother of four, fled her town after she was abducted and brutally attacked by paramilitaries. Plinio was trying to help members of his indigenous community go back to their farms when he received death threats from a splinter group of left wing guerrilla (the ELN) and his friend was assassinated.Their stories illustrate a nationwide trauma - the government may be on the brink of a historic peace deal with the FARC rebels, but Colombia has even more internally displaced people than Syria. More than 200,000 have been killed and seven million driven off their land during half a century of war. Lucy travels down the River Baudo to meet people uprooted from their jungle villages in violent clashes earlier this year and finds that Latin America's longest insurgency is far from over.Reported and produced by Lucy Ash.

Playing war-games in the woods has become an ever-more popular pastime in Poland as thousands of young people join paramilitary groups to defend their country against possible invasion. Others - so-called "preppers" - are building bunkers and storing food supplies so their families can survive any disaster. Now the government plans to recruit such enthusiasts into a state-run volunteer defence force - to counter a possible Russian threat. But are the authorities stoking fear - and creating an amateur force that's no use in 21st Century warfare? Tim Whewell reports from the forests of north-eastern Poland, close to the Russian border. Producer: Estelle Doyle.

Away from the sound of bombs and bullets, in the basement of a crumbling house in the besieged Syrian town of Darayya, is a secret library. It's home to thousands of books rescued from bombed-out buildings by local volunteers, who daily brave snipers and shells to fill its shelves. In a town gripped by hunger and death after three years without food aid, Mike Thomson reveals how this literary sanctuary is proving a lifeline to a community shattered by war. Produced by Michael Gallagher and additional research and translation by Mariam El Khalaf.*Omar, the FSA soldier pictured above who was the last voice heard in this programme has been killed in fighting.*.

Ed Butler explores the secretive and shocking world of Malawi's "hyenas". These are the men hired to sexually initiate or cleanse adolescent and pre-adolescent girls - some said to be 12 years old, or even younger. It's a traditional custom that is endorsed and funded by the communities themselves, even the children's families. We meet some of the victims, the regional chief campaigning to stop the practice, and the hyenas themselves, and ask if enough is being done to stamp out a custom that's not just damaging on a human scale, but is also undermining the country's economic development. Reported and produced by Ed Butler.

Chloe Hadjimatheou tells the astonishing story of a group of young men from Raqqa in Syria who chose to resist the so-called Islamic State, which occupied their city in 2014 and made it the capital of their "Caliphate".
