A town were spooked when they saw six strange lights in the sky.

The unusual sightings were captured by residents in Donji Milanovac in eastern Serbia and led the small area to believe they were being visited by UFOs, the Daily Mirror has reported.

The two-minute footage, which was captured on mobiles, was shared online on YouTube and depicts triangular shaped lights flying about in one specific area at 10pm before they shot off into another direction one by one.

However, other residents failed to believe the UFO theory and many social media users have claimed the supposed alien visitation were planes or stars.
