Drone seen over Islamic State-held territory in Aleppo, Syria

BEIRUT (Reuters) - At least one unmanned surveillance aircraft has been seen over Islamic State-controlled areas of the Syrian province of Aleppo, where the militants have evacuated most of their bases, a group which tracks the war in Syria reported on Thursday.

Rami Abdulrahman, who runs the Syrian Observatory for Human Rights, said multiple sources in northeastern Aleppo had spotted at least one drone over towns including al-Bab and Manbij. "They hadn't seen them before," he told Reuters by telephone.
