KENYA-AFRICA-UNREST-SUMMIT

Nigerian President Goodluck Jonathan addresses the opening of the African Union Peace and Security Summit in Nairobi on September 2, 2014. African leaders said the continent must work together to end the "scourge" of terrorism, amid fears of a growing extremist threat on the continent. The African Union summit in the Kenyan capital began hours after a US air strike in neighbouring Somalia reportedly targeted the commander of the Al-Qaeda-linked Shebab, one of several extremist groups plaguing the continent.
