Philip Hammond defends use of military drones
The controversial use of drones, or unmanned aircraft, in Afghanistan has been defended by the defence secretary.
Since earlier this year, the RAF has been flying "RPAS" or "UAVS" over Afghanistan from an airbase in Lincolnshire.
Defence Secretary Philip Hammond was visiting RAF Waddington in Lincolnshire, the operation centre of the UK drone programme.
