According to the latest news reports from Beijing, China will be deploying unmanned aircraft or drones over its Olympic sailing venue in Qingdao during the Games to watch for suspicious activities.

The state-run Xinhua news agency said that police tested one of the drones last Friday during a drill in the Shandong provincial capital of Jinan, not far from Qingdao. Reports say it is the first time that China has used the unmanned, low-flying reconnaissance aircraft.

Xinhua explained that the drones would scout out suspicious activity and transmit photos and video back to a command station. It did not say what threats the sailing event could face. China has said terrorism is the biggest threat to the Beijing games and already claims to have foiled terrorist plots targeting athletes and foreigners during the Olympics.
