Abuja, Jumada I 01, 1437, February 10, 2016, SPA -- Africa and Europe must work together to tackle terrorism and the causes of refugee flows, said German President Joachim Gauck Wednesday, speaking before the Economic Community of West African States in Nigeria, dpa reported. "Fleeing and displacement have become a challenge that quite directly links both our continents," Gauck said during his speech in Abuja. Germany wants to "remain an open country" for refugees, the president said. "But we also recognize that our reception capacity is limited. We cannot take in all who want to come to us." "Developing countries, emerging countries and industrialized countries can only together solve the many challenges that do not know national frontiers," he said, referring to climate change, the struggle for peace and the preservation of biodiversity. --SPA 15:58 LOCAL TIME 12:58 GMT www.spa.gov.sa/w
