Normally maritime exclusion zones are put in place down range when a rocket launches so that if it fails the debris can fall safely into the sea.

I wonder how Djibouti will manage this given that there are very busy shipping lanes going through the Gulf of Aden, just off the coast of Djibouti. Even ignoring that the range of orbits it can launch to will be quite limited unless they plan to launch over Somali or Yemeni territory.
