A second UFO has been spotted flying over Las Vegas, near where a family claimed they saw '8-foot tall aliens in their back garden.'

Video footage shows two beams of light can be seen in the sky, hovering next to one another on June 21, at 10.30pm.

The person who filmed the footage and shared it on social media claims the unidentified objects were in the sky above Las Vegas for '20 minutes straight'.

The footage was later followed by snaps of two interlocking white circular beams of light in the sky that were also spotted on Wednesday night by another local resident.
