ALEPPO, SYRIA - APRIL 14: Syrian people from the city of Douma arrive in Al-Bab district of Aleppo, Syria on April 14, 2018. The 20th 85-bus 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.
