Ban on killer robots urgently needed, say scientists

Technology now exists to create autonomous weapons that can select and kill human targets without supervision as UN urged to outlaw them

The movie portrays a brutal future. A military firm unveils a tiny drone that hunts and kills with ruthless efficiency. But when the technology falls into the wrong hands, no one is safe. Politicians are cut down in broad daylight. The machines descend on a lecture hall and spot activists, who are swiftly dispatched with an explosive to the head.

The short, disturbing film is the latest attempt by campaigners and concerned scientists to highlight the dangers of developing autonomous weapons that can find, track and fire on targets without human supervision. They warn that a preemptive ban on the technology is urgently needed to prevent terrible new weapons of mass destruction.
