6,000 IS jihadists could return to Africa: AU

Up to 6,000 Africans who fought for the Islamic State (IS) jihadist group in Iraq and Syria could return home, the African Union's top security official warned Sunday, calling on countries to prepare for the threat. Smail Chergui, the AU's commissioner for peace and security, said African nations would need to work closely with each other and share intelligence to counter returning militants.
