Fighting the propaganda war

Not only are the United States and Britain trying to pound the Taleban into submission, but now they want to win hearts and minds as well. A secretive branch of the American military, known as "Pyschological operations" - or psy-ops - has begun broadcasting pro-US, anti-Taleban radio messages from a US plane flying high over Afghanistan. The broadcasts are aimed at ordinary Afghan people, to try and win them over to the American cause, and encourage anti-Taleban dissent. Our reporter Andrew Bomford has been listening in.
