From Our Own Correspondent - 04/07/2009

BBC foreign correspondents with the stories behind the world's headlines. Introduced by Kate Adie. A sad week for the British army as the Taliban fight back; thousands of migrants, hoping for a better life in Britain, live in squalor in the woods outside Calais; President Obama travels to Moscow, keen to bury the lingering legacy of the Cold War. In Dubai, there's concern about events just over the Strait of Hormuz in Iran; and on Independence Day, reasons to be cheerful on the birthday of the United States.
