Militant groups like Hezbollah and the Islamic State have learned to weaponize surveillance drones and use them against each other, adding a new twist to Syria's civil war. The U.S. military is aware of the development, and commanders have warned troops to take cover if they see what they once might have dismissed as a surveillance drone, officials said. This newest development became reality this week when two French soldiers were gravely injured by a drone that exploded as they assisted Kurdish forces aligned against ISIS in Iraq.

Armed drones appear in a video belonging to an al-Qaida offshoot, Jund al-Aqsa, that purportedly shows such an aircraft landing on Syrian military barracks. In another video, small explosives apparently dropped by the Iran-backed Shiite militant group Hezbollah target the Sunni militant group Jabhat Fateh al-Sham, formerly known as the Nusra Front.
These are things that are normally beyond the capability of insurgents or terrorist groups.P.W. Singer, author of "Wired for War: The Robotics Revolution and Conflict in the 21st Century"
