Ten-year-old Abanoub Samaan Nazmy, right, holds a toy gun as he plays with his sister, who is studying in the living room of their home in Manshiyet Nasr on February 2, 2015. Abanoub lost his Coptic father to suspected military snipers as he protested in March 2011 over the burning of a church. The years of turmoil following EgyptÕs 2011 uprising have seen revolutionary graffiti come and go, but hidden scars remain for children who grew up witnessing violence and experiencing loss.
