Panorama: The Secret Drone War

America's CIA is fighting a secret war in the badlands of Pakistan - targeting al Qaeda and other militants with hellfire missiles in drone strikes that the UN says are illegal. No one knows the true number who have died, but it is estimated that the death toll may be around 3,000 - some of them, it is claimed, innocent women and children. Panorama goes to Waziristan, one of the most dangerous places in the world, to report on the drone war and to find out from its victims why they are seeking justice in the British courts.
