This baffling footage said to show a UFO tracking the International Space Station has emerged out of Russia.

It apparently shows a space shuttle-shaped craft following the Earth-orbiting satellite.

The footage - claimed to have been shot on the ISS's own cameras – is said to have been filmed while the satellite was waiting for a supplies delivery, according to reports in Russian media.

Astronauts on the film's soundtrack make no comment about the object seemingly observing them.

They can't, as they've signed strongly binding NDO's. ;-) To read more and view the video, click here.
