Mysterious spinning UFO during halo captured in Cuajimalpa, Mexico

A halo was seen from different places of Mexico. Mr. Gustavo Fuentes who was in Cuajimalpa in Mexico City recorded the halo and something that cannot be explained.

Inside the halo, several spherical objects were moving to the left side and at the end they go away at a high speed.

We can rule out that it is a reflection of the sun, because in the video you can see that the spinning objects stay in the same place while the camera is changing position while a camera reflecting on the right side is moving with the position of the sun.

Mr. Fuentes never saw the phenomenon during the video recording last year (May 21, 2015), he noticed it while checking the video afterwards.
