A Syrian child cooks in the street in a rebel-held area of Aleppo, on December 13, 2016, during an operation by Syrian government forces to retake the embattled city. UN chief Ban Ki-moon expressed alarm over reports of atrocities against civilians Monday, as the battle for Aleppo entered its final phase with Syrian government forces on the verge of retaking rebel-held areas of the city.
