US President Obama has outlined plans to limit the use of US drones, saying they must be targeted against terrorists when a threat was "imminent." Responsibility for launching a drone has been transferred from the CIA to the US Department of Defence. He said:
"To say a military tactic is legal, or even effective, is not to say it is wise or moral in every instance.
"Any drone strike will only be launched when a terrorism suspect cannot be captured. The United States will respect state sovereignty and will limit strikes to al Qaeda or associated targets.
"And before any strike is taken, there must be near-certainty that no civilians will be killed or injured - the highest standard we can set."
