Multiple witnesses have reported seeing these red lights in the dark cloudy skies of Sao Paolo, Brazil on May 12.
The video below shows the lights in an arc shape (possibly one circular UFO?) which are very visible in the dark clouds.
The video has its share of criticism though, with it being quite shaky, and the fact that Sao Paolo is so heavily populated, that this seems to be the only video so far. Check the video out below and share your thoughts: Real or fake?
