"The head of the United Nations food agency warned [today] that the relocation of Islamic State group members from the Middle East to Africa could trigger a massive new European migrant crisis," AP reports: "David Beasley, executive director of the World Food Program, said many of the militants who fled Syria amid the collapse of the Islamic State group's self-described caliphate had ended up in the greater Sahel region, a belt of semi-arid land spanning east-west across Africa."

Why it matters: "He said he has warned European leaders that they could face a far larger migrant crisis from the Sahel than the Syrian conflict generated if they do not help provide the region with food and stability."
