Refugees gather to watch the arrival of United Nations High Commissioner for Refugees Antonio Guterres at IFO-2 complex of the sprawling Dadaab refugee camp on May 8, 2015. Dadaab refugee camp currently houses some 350,000 people and for more than 20 years has been home to generations of Somalis who have fled their homeland wracked by conflicts. But Kenya's government asked the UN refugee agency (UNHCR) to close the camp after an attack on Kenyas Garissa University by Somalia-based Al-Shabaab gunmen in April, whom are suspected to have planned and launched their attack from the camp.
