The video that I retweeted earlier is one of those related of an alleged #UFO crash over #Brazil. Here's another one shared by many other Brazilian users about the same claim, but those lights are just skydivers with pyrotechnics.

One of those tweets with the same video that has gone viral. As I already said it's just a star/planet out of focus (Elon Musk and Starlink satellites have nothing to do with that). https://twitter.com/andredimauro/status/1260435268991102987
