UFO hunters have been examining viral video apparently shot this week in London, which a minority claim shows ‘orbs’ of alien origin in the skies.

Unusual sights have been reported in the seasonably inclement skies above England’s capital London in recent days. Amateur smartphone footage seems to show some anomalies glowing through the granite-coloured skies.

And some suggest at least three or four of them can be seen in the 57 second-long clip.

Self-titled expert in all things alien Scott Waring is among those who controversially think this unverified video has documented evidence of alien UFOs over London.

Mr Waring wrote a post on his UFO Sightings Daily blog, speculating about the provenance of these purported UFOs.

He said: “At least that’s what I get from past UFO video reports about a decade ago in Japan

“Here its [sic] London, but I reported the same white orbs over Mexico, Hawaii, Colorado, California and Japan […] all this week.

“So, you see, I have seen these orbs a lot in the last 15 years.

“And only seen a mother orb three times on video during that time.

“Rare, but the orbs you see in this video come from a mother orb releasing them one by one in this vicinity.“
