ALEPPO, SYRIA – APRIL 13: Syrian people from the city of Douma arrive in Al-Bab district of Aleppo, Syria on April 13, 2018. The 19th convoy carrying civilians and opposition fighters from the city of Douma in the Damascus suburb of Eastern Ghouta arrived in Aleppo’s Al-Bab district. Turkey’s Operation Euphrates Shield, launched in late 2016, liberated Al-Bab from the Daesh terrorist group. Home to 400,000 residents, Eastern Ghouta has remained under a crippling regime siege for the last five years, which has prevented the delivery of badly needed humanitarian supplies.
