A line of unusual lights has been spotted hovering in the night sky, with witnesses from both the US and Mexico claiming to have seen them.
Several witnesses have shared their videos online from the sight on March 31.
One video, posted to the Mutual UFO Network, shows four orbs appearing to change colour above Laguna Beach in California.
Another light then appears as the objects hovering in a perfect line.
Some 80 miles down the coast, another video emerged of the same sight over San Diego.
Again, the lights seemed to hover in a straight line before slowly disappearing one by one.
But it wasn’t just Californian residents that spotted the lights. Another 40 miles south of San Diego, in the Mexican city of Playas de Tijuana, a third video emerged of seven mysterious objects hovering in the same formation.
The collection of videos were shared online by YouTube conspiracy channel The Hidden Underbelly.
He wrote: “These lights seem to appear out of nowhere and were visible for about 15mins before disappearing one by one, leaving the witnesses puzzled and entertained by the aerial display performed by these orbs.”
Viewers flocked to the comments section to voice their thoughts on what they could be.
Some said they also saw the lights, with one writing: “Saw the same thing in Sacramento yesterday.”
Another added: “Whatever these things are, and whoever’s in them they must want to be seen.”
One suggestion was that they were simply Elon Musk’s Starlink satellites, which can often be seen in the sky.
While a fourth user suggested they could be military flares.
A similar explanation has been given in the past for UFO sightings but, as the user noted: “Why are people shooting multiple flares up all the time?”
It comes after a number of sightings of “red lights” over the US sent the conspiracy world into a frenzy.
Earlier this month, the cluster of red lights were seen moving “in formation” over Texas.
And several days earlier, the same objects seemed to appear above Washington.
