Channel 4 Unreported World: The Fish Bombers (2016)

Ade Adepitan travels to Tanzania, where 400 women died in witch-hunts last year, twice as many as in the year before. Many others were attacked and ostracised. More people in Tanzania believe in witchcraft than anywhere else in Africa. But some people think that there's more behind recent witchcraft attacks than a fear of the supernatural.

Seyi Rhodes and director Kate Hardie-Buckley report from the set of the hit South Korean TV show that's made defectors from North Korea into TV stars. Now on My Way to Meet You mixes showbiz entertainment and shocking personal testimony, with South Korean celebrities quizzing the defectors on what life's like across the border. More than 400 defectors have been interviewed on the show. Their stories chart the very latest about life in North Korea under Kim Jong-un and for many South Koreans it's become a major source of information about their northern neighbour.

In a summer of hurricanes and floods around the world, the incident that has taken most lives has been little reported. On 14th August, torrential rain triggered a huge mudslide that destroyed the small town of Regent on the outskirts of Sierra Leone's capital Freetown. Some estimates put the number of dead at over 1000, and the difficulties in recovering bodies means that the true figure may never be known. Reporter Seyi Rhodes travelled to the country just days after the mudslide, witnessing the terrible destruction and spending time with the survivors and rescue teams as he investigated the causes and devastating results of this natural disaster.

Sophie Morgan and director Patrick Wells visit the Samoan islands in the middle of the Pacific Ocean to investigate an epidemic of obesity. American Samoa has the highest rates of obesity in the world: up to 93% of people are overweight or obese and one in three have diabetes. Samoa is not far behind. The governments of Samoa and American Samoa are trying to tackle the crisis but both remote Islands are still being flooded with unhealthy processed food from abroad, as well as fatty offcuts of meat that are seen as unfit for human consumption in many other countries.

Seyi Rhodes and director Jessica Kelly are in Senegal to explore the national obsession with competitive wrestling. It's one of Senegal's fastest growing sports and offers young men the opportunity to earn big money in a country battling poverty and unemployment. Unreported World meets some of the superstar wrestlers treated like gods and worshipped by entire neighbourhoods, as well as up-and-coming fighters pushing their bodies to the limits in the hope of making enough money to support their families.

Sophie Morgan reports from Australia where leaked footage of the shocking treatment of young prisoners - most of them Aboriginal teenagers - in a juvenile detention centre in the county's Northern Territory has sparked outcry and a government inquiry. Ninety-four per cent of young people held in detention centres in the Northern Territory are Aboriginal, although they make up only a quarter of the state's population. Morgan and director Simon Rawles meet one of the boys at the centre of the scandal, who reveals his harsh treatment behind bars.

Unreported World meets some of Russia's most prolific parents and investigates a wave of intolerance sweeping the country. The resurgent Russian Orthodox Church is at the forefront of a new movement combining religion and nationalism. In Rostov on Don, Marcel Theroux and Jessica Kelly meet an Orthodox family with 18 children who have received medals from the government and cash from some of the country's richest people, who are keen to associate with the values that President Putin is promoting: family, God and country.

India has long struggled with religious violence, but in recent months the problem has taken a gruesome new form. Across the country, gangs of Hindu men have lynched Muslims who they accuse of killing cows or eating beef. Known as cow vigilantes, in some instances mobs have killed or injured more than 150 people since 2015. India's Prime Minister, Narendra Modi, has made a plea for calm, but 2017 is set to be the worst year for attacks to date. Reporter Mirren Gidda meets a group of vigilantes, unconnected to any killings, who take her on one of their nightly hunts for people who may be harming cows.

Unreported World explores the extraordinary world of China's up-and-coming pop stars. China's aspiring musicians are global citizens, inspired by US hip-hop, British punk and the slick routines of Korean pop. But as reporter Marcel Theroux and director Sarah Collinson reveal, they face the special challenges of working under increasing censorship and a deeply authoritarian government.

As the Republic of Ireland prepares for a referendum on whether to alter legislation that makes abortion illegal in almost all circumstances, reporter Shaunagh Connaire and director Kate Hardie-Buckley meet women and families on both sides of the debate, and document the dilemmas medical staff face working under the current laws, in this moving and powerful episode.
