What about misused or defective radio equipment ? I guess that they have powerful microwave sat equipment, in there. This is a more reasonable explanation then mysterious "death ray" that, anyway, should be detectable and traceable with the right equipment, in case someone want to prove its existence. Moreover, what's the logic in creating a gratuitous diplomatic incident and possibly cause reprisals against the responsible ? IMHO , this story is the perfect click bait so nobody want to consider more logic and simple explanations.
