UN Calls for Action on Landmine Deaths Among Displaced in Sahel, Lake Chad Regions Lisa Schlein GENEVA - The U.N. refugee agency is calling for urgent action to stop the killing and maiming of refugees and other forcibly displaced people from landmines and improvised explosive devices in Africa's Sahel and Lake Chad basin regions.
