Mysterious metal balls in Vietnam space debris or alien activity?

Falling space debris is a common phenomenon often reported by countries.

On Thursday, Northern Vietnam reported falling of three strange objects from space.

The spheres, which weighed 250 grams, six kilos and 45 kilos, were found at three separate locations by the defence.

According to initial investigation, the components are not explosive and could have been made in Russia and come from missiles or spaceships.

Some also debate that they could have been used as compressed air equipment.

The objects will now be reported to the Council of National Defense and Security.

According to the locals, "The first sphere, around six kilos in weight, flying at around 6:30 a.m. before it crashed down on a garden in Yen Bai Province. The loud noise prompted them to run away."

Many locals reported to have heard several thunder-like noises from the sky just minutes before the objects were discovered.
