A girl writes her name on a dusty mirror in the largely destroyed part of Aleppo city in northern Syria, Dec. 21, 2017. Last year's battle of Aleppo was so cubical and a turning point in the course of actions in the Syrian crisis, due to the strategic importance of the city, which was the economic capital of Syria and where most of the country's industry was located.
