A girl waves goodbye to a volunteer as Algerian police officers escort migrants to a bus at the Zeralda migrant center, 30 kilometers (18 miles) outside Algiers, Thursday, June 28, 2018. About 400 migrants, mostly from Niger, were moved to Tamanrasset, southern Algeria, near the border with Niger. Algeria has abandoned more than 13,000 people in the Sahara Desert over the past 14 months, including pregnant women and children, expelling them without food or water and forcing them to walk, sometimes at gunpoint, under a blistering sun.
