Jonathan Marcus: Deadly potential of 'off-the-shelf' drones

You could call it a demonstration of the proliferation of drone use with frightening possibilities. Last week's attack in northern Iraq in which a small drone exploded killing two Peshmerga fighters and badly wounding two members of the French special forces, marks something of an innovation in modern warfare. The US launched the first armed drone attack back in October 2001. Since then the use of armed drones has been the preserve of the most sophisticated military actors in the world. Israel and the US had the early technological lead with Russia and China rapidly developing their own drone industries.
