This World

In November 2015, when gunmen attacked Paris, France declared war on the Islamic State. But that war - and France's 'year of terror' - began a year ago with the attack on satirical magazine Charlie Hebdo.

With unprecedented access to the French authorities and previously unseen footage, five-time Bafta-winning director Dan Reed reveals the untold story of the massacre and of the first Islamic State strike in Paris at a kosher grocery store.

Key witnesses, police officers and survivors - many speaking for the first time - piece together the dramatic attacks and the unprecedented manhunt that gripped the world for three extraordinary and terrifying days.

Following the crisis in Ukraine and Russia's involvement in Syria, the world is closer to superpower confrontation than at any time since the end of the Cold War. Now, a war room of senior former British military and diplomatic figures comes together to war-game a hypothetical 'hot war' in eastern Europe, including the unthinkable - nuclear confrontation.

Robert Preston presents a show exploring China's dramatic economic slowdown and the impact that it could have on Britain.

Reggie Yates investigates the reality behind the global super-rich's insatiable appetite for luxury goods. Top of the list are animals, but how much do we really know about where exotic skins and furs come from? And what is the real cost? To find out, Reggie visits Siberia in search of the world's most expensive fur.

In Australia he discovers the reality behind croc farming, and in Indonesia he goes deep into the forest in search of the pythons that end up as bags and phone cases. But how far can this trade go? As the fashion for animal products trickles down to the high street, is it sustainable?

The BBC's award-winning This World strand goes inside the world of Romania's super-rich Gypsy popstars - a world of fast cars, lavish houses and gangsters.

The Roma community is one of the most marginalised and impoverished in Europe and for years their traditional music has been their most famous export. Now a new type of Gypsy sound called Manele has swept across the country. Manele stars can earn 20,000 euros a night at opulent weddings, with cash showered over them by guests. Their videos can get millions of hits on YouTube.

But Manele is controversial - some of its lyrics glorify gangsterism and some of its biggest fans are notorious underworld figures. Filmmaker Liviu Tipurita takes us into the heart of this extraordinary world.

America's college fraternities are notorious for hard drinking and hard partying, but they are also accused of fostering a culture of brutality and sexual assault. During one term at the University of Central Florida, the BBC's award-winning This World programme follows the life of a group of frat boys as they embark on the pledging process, when new recruits have to prove themselves before they can become a fraternity brother.

Most kids are joining because fraternities provide access to a powerful network of alumni throughout the US. But each year, students die or are injured in barbaric initiation rituals, known as hazing, and some argue that the way fraternity system is set up allows sexual assaults to occur during drunken campus parties. Research has shown that fraternity men are three times more likely to sexual assault than non-fraternity men.

Film following the murder trial of a white police officer in Portsmouth, Virginia, accused of shooting an unarmed black teenager. On 22 April 2015, Officer Stephen Rankin responded to a report of shoplifting at a Walmart store. Minutes after arriving in the parking lot, he shot and killed William Chapman.

After Chapman's death, Rankin was fired from Portsmouth Police Department and charged with first-degree murder. Chapman was just one of 306 black men who were killed by police in the US last year, but just 14 police officers faced any charges - Rankin was one of them.

With extraordinary access to the prosecution and defence, as well as Chapman's family and friends and those closest to Officer Rankin, this powerful 90-minute documentary from award-winning filmmaker James Jones forensically follows the drama as the trial unfolds and unpicks Rankin's troubling prior record in the police department.

During a summer of increasing tension across America, this film explores the reaction of a divided community to the prosecution of a local police officer. Part of the award-winning This World strand on BBC Two.
