In a rundown neighbourhood in Athens there is a hotel with 4,000 people on its waiting list for rooms. But the roof leaks and the lifts are permanently out of action. None of the guests pay a penny, but everyone's supposed to help with the cooking and cleaning.

Why is troubled Catalonia now opening up civil war mass graves?

Spain has the second largest amount of mass graves in the world after Cambodia. Over 100,000 people disappeared during the 1930s civil war and the ensuing Franco dictatorship. Decades later, the vast majority are still unaccounted for.

Forgetting Spain's painful past and the disappeared is what allowed democracy and peace to flourish, the argument has long gone.

But many have not forgotten - including in the region of Catalonia, where bitter memories of Franco's rule are just beneath the surface. Before Madrid imposed direct rule last October, the pro-independence Catalan government began an unprecedented plan to excavate civil war mass graves and collect DNA from families looking for their lost relatives.

Estelle Doyle travels to the politically troubled region and finds out how, despite direct rule, those seeking answers are more determined than ever to recover the past and to confront Spain's painful history. Others worry that their actions will only but reopen old wounds and further divide the country.

For nearly two decades, Swedish health professionals have been treating asylum-seeking children who fall into a deeply listless state. They withdraw from the world, refuse to speak, walk and eat - most end up being tube-fed. They are known as, "the apathetic children" in Sweden. More recently this illness has been termed Resignation Syndrome. Experts agree it is children who have experienced deep trauma who are vulnerable. Doctors link the condition to an uncertain migration status. But why, asks Linda Pressly, does it only seem to happen to children in Sweden, and how can they recover?

Lucy Ash meets the staff and customers of a bakery which is the one bright spot in war-torn east Ukraine. The war there between Russian-backed rebels and the Ukrainian army has dropped out of the headlines and there seems to be little political will to make peace. More than 10,000 people have been killed and as it enters its fourth year, this has become one of the longest conflicts in modern European history. But in the frontline town of Marinka there's one bright spot amidst the gloom - the bakery. It's the first new business in the town since the fighting began and it is bringing some hope and comfort to its traumatised citizens. We meet staff and customers from the bakery to explore a community living on the edge. "The aroma of fresh bread," says the man behind the enterprise, " gives people hope. It smells like normal life."

For decades, Brazil has presented itself as a colour-blind nation in which most citizens are, at least to some extent, racially mixed. But a controversial education law is encouraging black Brazilians to assert their own distinct identity. Federal public universities now have to comply with government quotas for black students, as well as others deemed to be at risk of discrimination. Yet, since the rules allow applicants to self-define their colour, there have been numerous alleged frauds, and some universities are now creating inspection boards to assess students based on whether they appear phenotypically black. On the political right, there's a backlash among those who say the quotas are divisive and even racist. While some people of mixed race complain that they are 'not black enough'. But many black Brazilians themselves say they finally have a reason to acknowledge their ethnicity in a country where privilege all too often belongs to those of European descent. For Crossing Continents, David Baker reports on an issue that is at the heart of what it means to be black in Brazil.

A journey up the 'suicidal' Pilcomayo river that separates Paraguay from Argentina... The Pilcomayo is the life-force of one of Latin America's most arid regions. But it is also one of the most heavily silted rivers of the world. As it courses down from the Bolivian Highlands in the months of December and January, half is water, half sand. This means it often causes flooding. Or, it changes course, failing to deliver water to those who depend on it. So in order to benefit communities, this is a river system that needs careful management, and a lot of human input to ensure the water flows. Compounding the fickleness of the Pilcomayo are 3 years of drought in the region. Gabriela Torres travels north from Asuncion up the course of the Pilcomayo during the dry season, visiting communities where the wildlife is dying and the economy under threat. How will the people - and animals - cope this year?

There are 33 ways to dispel a mistress according to one of China's top love detectives. An unusual new industry has taken hold in some of the country's top cities. It's called "mistress-dispelling", and it involves hired operatives doing what it takes to separate cheating husbands from their mistresses. With the surge in super-affluent families in China, there has also been an apparent upsurge in the number of men choosing to keep a concubine. And for wives who see divorce as a humiliating option, almost no expense is sometimes spared in seeing off the rival. For Crossing Continents, Ed Butler meets some of these private detectives and "marriage counsellors", heads off on a mistress "stake-out", and asks whether this is all a symptom of a deeper crisis in gender relations in China.

The brutal, unsolved murder of Malta's most outspoken blogger has blackened the image of the Mediterranean holiday island. Since Daphne Caruana Galizia was blown up by a car bomb in October, her son has denounced his country as a mafia state. European leaders say they're deeply concerned about the rule of law there. But on Malta, Daphne was a divisive figure - admired by some as a fearless investigative journalist, detested by others as a snobbish "queen of bile." She herself said there were "two Maltas" - and the reaction to her murder has proved that. So was Daphne's death a political assassination - as one Malta says - or a criminal killing without wider implications, as the other Malta insists? Tim Whewell goes looking for answers on an island where everyone knows everyone, but belongs firmly to one camp or the other. Producer: Estelle Doyle.

As they retreat from Northern Iraq so-called Islamic State has left thousands of women and children behind. Some are the abandoned families of IS fighters, others are being held as prisoners or slaves. There are also boys who were forced to fight for IS. A desperate effort is now underway to reunite these women and children with the families they have been separated from - and to rehabilitate those whose minds have been stolen by the group. Tim Whewell reports from Iraq on the children left behind by the fighters of Islamic state.

In the West Bank hundreds of families share a passion for breeding horses. Amid the narrow streets and cramped apartment buildings small stables can be found with owners grooming beautiful Arabian colts and fillies. These new breeders are now making their mark at Israeli horse shows where competition to produce the best in breed is intense. As Palestinian and Israeli owners mingle on the show ground, political differences are put to one side as they share a passion for the Arabian horse.
