There is even a small, and unofficial, CIA base in Mogadishu, the traditional capital of Somalia. The CIA, and similar outfits from other nations, also work from Djibouti. But most of the effort is directed at monitoring what is going on in the region (mainly Somalia and Yemen but also Eritrea, Nigeria, Mali, Libya, Kenya, and Ethiopia) not at interfering with the local terrorists. Not much, anyway. The Djibouti base also supports operations throughout the Sahel (the semi-desert strip between the North African desert and the Central African jungles, which stretches from the Atlantic to Somalia).
