The origin of a series of lights spotted glowing eerily through the clouds over Kent remains a mystery.
The UFOs were reported hanging in the sky over Hythe and Folkestone by several people, with a series of sets appearing over the course of 30 minutes.
One theory is the lights are flares, used by armed forces to illuminate areas of a battlefield.

And the nearby military ranges at both Hythe and Lydd would seem to make this an obvious explanation.
However, the MoD says no flares were being used at its firing ranges in the area.
A spokesman confirmed there was no activity on Lydd Ranges on Sunday morning when the lights were spotted at about 10.30am.
They added that although there was some activity on Hythe Ranges, it did not involve flares being fired.
Watch: Mystery lights spotted over Hythe
Whether the lights are flares or not, their origin remains a mystery, and it's not the first time strange lights have been spotted over the county.
A spokesman from Kent Unidentified Flying Objects Research Group said: "The coastlines around East Kent and South Kent are major UFO areas.
"The towns in these areas have large amounts of UFO sightings on a continual basis.
"People are observing UFOs over the Thames Estuary and the English Channel all the time. UFO sightings in these areas have increased dramatically in the past few years."
