Laser canon and sonic death rays.
As the story notes, loads of these incidents happen in the US all the time. They are caused by scrotes with laser pointers. I don't see why Djibouti would be any different and I suspect that the importation of laser pointers in terms of power and frequency sees a lot less regulation there.
This smacks of the American story about the Cuban sonic death ray supposedly being directed at their embassy personnel in Havana. That would be the Cuban sonic death ray that no other country finds credible. Canada has investigated it and come to the conclusion that the sonic weapons theory isn't plausible. The Americans none the less persist in blaming Cuba.
