Mysterious red flashes spotted streaking across the sky during thunderstorm prompt fears of alien spaceship invasion

Flashing red-lights spotted in the sky sparked fears of a landing by UFOs and invasion by extraterrestrials. Several residents in Budapest, Hungary, described a "UFO landing" - following a late-night thunderstorm in the country.

Martin Szoter captured mystery red lights in the sky from near where he lives in Budapest's 21st district, Csepel. Martin believed it to be a crash landing - and that there may have even been more than one extraterrestrial visitor.

UFOs landed in Budapest XXI. District, in the thunderstorm," he wrote.

But Martin was far from the only person to witness the mysterious light source.

Online user 'HU MFM' noted that they saw this strange phenomenon "five times", calling it a "red 'something'" appearing before every lightning strike.

There has been no official explanation from local officials or meteorological experts.

Residents have been left to speculate that it could have been an alien landing - or something as simple as a blown transformer causing the eruption of red light.
