Many of Aleppo's historical sites, including its famed  Al-Madina Souq market and the Umayyad mosque, were badly damaged during Syria's civil war. According to UNESCO, 60% of the old city of Aleppo has been severely damaged, with 30% totally destroyed. People now start returning to their homes in east Aleppo that was held by rebels for more than four years until government forces took full control of it. Aleppo's historical sights after Syria civil war - in this photo gallery.
