Three ‘bizarre objects’ fell from space over Thailand - 100lb, two-foot metal orbs made of a metal alloy.
One fell on remote land in Tuyen Quang Province, and a smaller orb fell on a garden in Yen Bai Province.
One local witness told Thanh Nien ,’The sky was clear, suddenly we heard a thunder-like noise.’
Similar metal orbs have fallen over Australia and Europe in recent years - with a crop of mysterious metal balls found in Spain last year.
The objects weigh about 100lb each - and defence officials say that they are compressed-air tanks from an aircraft or rocket and were probably manufactured in Russia.
Aerospace expert Prof Nguyen Khoa Son says that the objects may come from a satellite - either from a failed launch, or from an old satellite which failed to burn up in Earth’s atmosphere.
