Eerie footage of a white orb of light flying through the sky has been filmed close to South America's highest monument.
An eyewitness captured the dramatic footage on his phone from the observation windows of the 272-foot Cruz del Tercer Milenio - Third Millennium Cross, in northern Chile.

The clip was later posted on social media and video-sharing platforms where it sparked a lively debate and made national headlines.
