Syrian children attend the first day of school in a rebel-held area of the northern city of Aleppo, on September 6, 2014. Following an initiative from Syrian activists to set up a field school for the younger children, classes are taking place at a residential building which was deserted by its residents after the start of the three-year long conflict.
