London: Unmanned drones carrying deadly poison could be used in a terrorist attack during the Olympic Games, a senior army officer has warned.
Lieutenant Colonel Brian Fahy delivered the grim warning at a meeting intended to allay the fears of residents worried about the army`s plans to place missiles on the rooftops of flats, Daily Mail reported.
He said it was "feasible" that remote-controlled aircraft filled with poison and small enough to fit into a backpack could be used as a biological weapon in London.
He told The Mail on Sunday: "An unmanned aerial vehicle (UAV) can be put in a backpack. They come in all sorts of sizes and it`s feasible they could be filled with something noxious and flown by remote-control."
Lt. Col. Fahy, the officer responsible for community relations during the Games, made his remarks Friday in East London near one of six sites which could see the deployment of surface-to-air missile batteries in order to shoot down aircraft attempting to infiltrate an Olympic "No Fly" zone, the newspaper added.
