Displaced families queue for water at a collection point set-up by a UN aid agency on March 14, 2017 at a makeshift camp on the outskirts of Baidoa, in the southwestern Bay region of Somalia, where thousands of people arrive daily after they fled the parched countryside. The United Nations is warning of an unprecedented global crisis with famine already gripping parts of South Sudan and looming over Nigeria, Yemen and Somalia, threatening the lives of 20 million people. For Somalis, the memory of the 2011 famine which left a quarter of a million people dead is still fresh. / AFP PHOTO / TONY KARUMBA
