Footage of a UFO moving slowly across the sky before suddenly vanishing has sparked a debate on social media.
The flying saucer was spotted above the mountains near the city of El Alto, in the north-west Bolivian department of La Paz.
The footage shows the circular-shaped object, which disappears and reappears among the clouds, high above a rural neighbourhood on the outskirts of the country's second largest city.

One user summed it up by writing: 'Not sure what to think of this one'.
El Alto is located adjacent to the city of La Paz in the Pedro Domingo Murillo Province on the scenic Altiplano highlands.
