With the increasing rate of insecurity across African continent especially terrorism as a result of massive refugee influx, many of African countries are worried about the impact the refugees have on the national security of the countries they seek asylum. This concern prompted me to carry out my research on the security challenges in Africa focusing on the role of refugees in Kenya. I was guided by the following set of questions: What is the impact of refugee influx on African security? What has been the trend and impact of refugee influx on Kenyan security? And what strategies and mechanisms has the Government of Kenya employed to combat insecurity especially terrorism as a result of refugee influx in Kenya? which were used to formulate my objectives: To examine and analyze the impact of refugee influx on African security; to examine and assess the trend and impact of refugee influx on Kenyan security; to analyze strategies and mechanisms the Government of Kenya has employed tocombat insecurity especially terrorism as a result of refugee influx in Kenya.
