Not always!
If a picture doesn't have provide a light source for every object then Lens Flare can be thrown out in many cases.
Take the OP's examples. Crop out the bright artificial light sources. There, and voila! Now a person came claim the lens flares as a "UFO".
Alternately, the photographer can do some "in camera" cropping, merely by framing his shot in such a way that the light source(s) is(are) not in the photo.
This is the basis for many of the lens flare-type claims that infest this field of study.....whether honest mistakes, or intentional hoaxes.
