The Wagner mutiny in Russia; and other stories from Russia, Peru, Bangladesh and Denmark. The mutiny by Russia's Wagner mercenaries ended as quickly as it started. The fighters had taken the southern Russian city and military hub Rostov-on-Don, and were heading for Moscow, when their leader called it all off. How do the capital's residents view these events? Russia says it has lost 6000 soldiers in Ukraine, but the true figure is thought to be 40,000 to 60,000. Olga Ivshina has been tracking her country's military fatalities with other volunteers, and has so far counted 25,000. Sometimes their relatives didn't even know they had died. Peru is suffering its worst outbreak of dengue fever on record, following unusually hot and wet weather conditions. The viral disease is carried by mosquitoes and can cause severe joint and muscle pain, even death. Dan Collyns travelled to the centre of Peru's epidemic in Piura in northern Peru. Bangladesh used to have high rates of pregnancy or childbirth-related deaths, and of children dying in infancy due to low rates of vaccination. But now illness and deaths have been drastically reduced, thanks to the "disease detectives" scheme - women offering healthcare to millions. Peter Young went to see how it works. Denmark's small prison population has been growing due to harsher sentencing, but the number of prison officers is falling, leading to concerns about overcrowding, and the quality of the prison regime. Polina Bachlakova found the impact is even felt in a prison’s choir.
