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.
'Drone strike killed my grandmother outside our house'
Over the past eight years, there have been more than 300 American drone strikes against al Qaeda and other militant targets in Pakistan's tribal areas.
While the US says it is a precision tool that is helping them to win the war on terror, others say the unmanned planes that drop bombs are being used indiscriminately - resulting in untold civilian casualties.
