“Vietnamese military are studying mysterious space balls that have fallen from the sky.”

The local newspaper Thanh Nien has rushed to report that a preliminary investigation has concluded the Russian origin of these strange balls, and that they may be part of missiles or a spacecraft. Why such a conclusion was made is not yet known, since no identification signs are visible on the photos of the balls.

From the comments:

- With the last transport ship "Progress" to the ISS was delivered 5 balls intended for scientific experiments. Two of them were broken and three lost.
