More than two weeks after the floods that swept through the Valencia region of Spain, the streets are still being cleared of mud and debris. More than 220 people are known to have died but many more have lost their homes and businesses. In our conversations, a family shares their experience of searching for their father and we hear how a mother is struggling to come to terms with the events she witnessed. Meanwhile, recriminations are flying over who is to blame. Officials are facing criticism for failing to issue a weather warning to people’s phones in time, and for the slow mobilisation in the aftermath of the disaster. Three volunteers who have been helping with the rescue effort share their frustrations with the government response.

At the age of 34, Donna Mulhearn – a committed Christian - had grown disillusioned with her career as a journalist and political adviser. When she heard someone on the radio seeking volunteers to serve as human shields in Iraq, Donna - already opposed to the war and a staunch advocate of non-violent action - immediately knew what she had to do. Despite the objections of concerned family and friends, she travelled to Baghdad to join hundreds of other volunteers from around the world. But all too soon things got complicated. The Iraqi authorities had their own ideas about where the human shields should be deployed – and then Donna, along with other volunteers, witnessed scenes of carnage. Despite all this, Mike Wooldridge, asks, does she feel with hindsight that she did the right thing?

You can spend hours in an airport and never learn anything about the people around you. But follow the chaplains of London Heathrow, and you might start to see things - and people - differently. Headed up by Reverend Ruth Bottoms, a team of 20 multi-faith chaplains offer sanctuary and support to passengers and staff in the unpredictable environment of a mega airport. Counselling nervous fliers, responding to crises, leading daily masses in Heathrow’s own chapel - these chaplains respond to whatever comes their way.

Jude Shapiro spends a week with the chaplains and those they encounter to see what happens when faith, flight and the stresses of Europe’s busiest airport combine.

With thanks to the Heathrow Multi-Faith Chaplaincy and Heathrow Airport.

A historic trial is underway in Sweden. Two European executives of a Swedish oil company are accused of aiding and abetting war crimes in South Sudan.

Sydney has one of the most recognisable opera house in the world, but some of the most innovative opera-making is happening at the other end of town, in the building where they used to build train carriages. Sydney Chamber Opera, led by o Jack Symonds, is a young, experimental collective of opera makers, collaborating with the established national company Opera Australia to bring Jack's epic Gilgamesh to the stage. Directed by Kip Williams, it is a new opera based on a very old story of queer desire, environmentalism, and dancing scorpions. Ce Benedict follows Gilgamesh from pianos falling through floorboards in rehearsals, to Opera Australia's artistic director unexpectedly stepping down, through to the literal glitter of opening night.

On 20 January, Republican Donald Trump will be sworn in as the 47th president of the United States. His domestic pledges include promises to bring down prices, tackle immigration, introduce tariffs on imports, and cut tax. Throughout the election campaign, we have been hearing from people from across the US - Republicans, Democrats and those who were undecided – about the issues that matter to them. In the lead up to the election, we heard from American voters from across the political spectrum and, this time in our conversations, host Mark Lowen hears widely contrasting views on the future of the country.

Twenty years ago, one man took it into his hands to educate Arab-Israelis about the Holocaust and its ongoing psychological effects. Khaled Kasab Mahameed, a lawyer from Nazareth, opened what is believed to be the first ever Arab-led Holocaust museum. His aim: to open the eyes of his fellow Arabs to the trauma of the Holocaust while at the same time reminding Jewish Israelis of the suffering of his own Palestinian people. Mike Wooldridge hears Khaled’s story and discovers why, despite his enormous idealism, he soon found himself the target of criticism from both sides of the conflict.
