Iran War: Pakistan the peace broker

Available for over a year

Kate Adie introduces dispatches from Pakistan, the Turkey-Iran border, Kenya, Ukraine, and Paraguay. Why was Pakistan chosen as the host of peace talks between the US and Iran? It's a question some in Islamabad have been asking themselves - and has fired-up a sense of national pride. Caroline Davies has watched on as the country gets ready for another round of negotiations. When the war in Iran began, there was a sense of jubilation among some Iranians, who had long-dreamed of the regime falling. Now that seems like a distant reality, and the mood is changing. BBC Persian's Omid Montazeri has been on the Turkey-Iran border, where he has found attitudes towards the war are shifting. This weekend marks the 40th anniversary of the nuclear disaster in Chernobyl, which remains the world's worst nuclear accident. Jordan Dunbar visited the city of Slavutych in Northern Ukraine, which was purpose built to rehouse workers evacuated from the power plant city of Pripyat - and recounts his search for a DJ legend of the 1980s. In northern Kenya farmers and their families are suffering the effects of consecutive seasons of low rainfall. A new report estimates around 400,000 people are experiencing acute levels of hunger. Sammy Awami reports from Turkana, one of the worst affected areas. And the semi-arid lowlands of the Gran Chaco span an area of around 280 thousand miles across South America - more than half of that is in Argentina, a third in Paraguay and the remainder in Bolivia. It’s the region’s second-largest forest ecosystem after the Amazon – and is also home to a wide range of animal, bird and plant species - as Sara Wheeler discovered.
