From Our Own Correspondent

Correspondents around the world tell their stories. In this edition Gabriel Gatehouse is back in Tripoli as speculation grows about a new military intervention in Libya; Mark Lowen is in Diyarbakir where there's been intense fighting between Turkish security forces and Kurdish militants; Miles Warde is in a dusty town on the edge of Kenya where there are plans for pipelines, resort cities and Chinese-built railways but the locals wonder if any of them will ever materialise; Claudia Hammond visits what they call a 'geriatric rehabilitation centre' in Cuba where, apparently, there's never a dull moment and Victoria Gill is in Antarctica meeting the rather amusing residents of a place called Moot Point
