CAIRO, June 20, 2016 (Xinhua) -- Children stay in the classroom before class at African Hope Learning Center in Cairo, Egypt on June 20, 2016. In the heart of Cairo's Maadi, one of the Egyptian capital's upscale districts, lies a two-story villa that is quite indistinguishable from other buildings in the neighborhood. The property used to house a family of 10, but with its bedrooms refurbished into classrooms and a small garden into a playground, it is now occupied by African Hope Learning Center (AHLC) and caters for 500 students, most of whom are refugee children from Africa. Founded in 1998, AHLC is a sponsor-backed institution dedicated to providing displaced African children in Cairo with access to primary and high schools. After a brief summer holiday, around 30 children came back to attend the center's summer school on Monday, coinciding with the United Nations' World Refugee Day. (Xinhua/Zhao Dingzhe)
