In a visit to the sprawling Dadaab refugee camp on the Kenya-Somalia border in advance of World Refugee Day on Friday, the UN refugee agency chief, António Guterres said a political solution must be found to end the violence in Somalia and he acknowledged that UNHCR had to do more to help those uprooted by the 17-year conflict. Dadaab hosts 200,000 refugees with 20,000 new arrivals from Somali since January.
