Beirut: At least one unmanned surveillance aircraft has been seen over Islamic State-controlled areas of the Syrian province of Aleppo, where the radical group has evacuated most of its 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.
US President Barack Obama last month authorised surveillance flights in Syria. Unmanned surveillance aircraft have already been spotted over the city of Raqqa, the Islamic State`s stronghold in Syria 450 km (250 miles) northeast of Damascus, activists have reported.
