Kate Adie introduces correspondents' stories from around the world. Today Rajini Vaidyanathan returns to the scene of the shooting in Charleston, South Carolina; Julia Langdon hears from the local people of Corfu on their five years - and counting - of economic misery; Lawrence Grissell speaks to widows in Nepal who are trying to find out what happened to their relatives who died while working overseas; David Shukman travels to one of Madagascar's most remote corners where tortoises are being protected with the help of a two-headed bull; and Mario Cacciottolo is in Malta, talking to hunters, who balance a passion for nature with an urge to shoot wild birds.
