WASHINGTON, Sept. 4 (UPI) -- The United States tracked al-Qaida efforts to find a defense against drone strikes, documents leaked by former national security contractor Edward Snowden show.
The Washington Post reported Tuesday the leaked classified documents suggest the terrorist group has had no success so far, with no evidence any drones have been shot down or destroyed. The documents include a report titled "Threats to Unmanned Aerial Vehicles" that contains intelligence on al-Qaida's efforts from 2006 on.
