Legality of US drones questioned

Missiles fired from US drones killed at least six people on Tuesday in a Pakistani tribal area bordering Afghanistan, according to security officials. It's the latest in a wave of attacks that have been used to target alleged enemy combatants but which frequently kill innocent civilians. The latest strike came as a congressional committee in Washington DC heard evidence that legal issues surrounding the use of unmanned aerial vehicles (UAVs) or drones have not been fully worked out.

A lone protester was told by the chairman: "You're going to have an opportunity to sit down or be asked to leave - it's your choice." She sat down but soon left the room, allowing the door to slam behind her. The committee went on to hear that while the US has more than 7,000 UAVs and more on order, there is still no legal framework for the operation of this new technology.
