KILLER robots that make their own decisions need to be banned urgently or humans face mass murder, desperate campaigners have pleaded.

Gruesome footage put together by AI experts shows small drones descending on a classroom and killing pupils by blowing up their heads.

The film – to be show to United Nations (UN) today – stresses the danger of autonomous weapons that pick and destroy targets without instruction.

It comes amid the advancement in AI weapons deployed by nations at war.

AI scientist, Stuart Russell, will present the film today at the UN Nations Convention on Conventional Weapons hosted by Campaign to Stop Killer Robots.
