Vietnam’s military is investigating the appearance of three mysterious metal balls — believed to be debris from space — which landed in the country’s remote north, a senior army official said Friday.
Two metal balls were discovered in northwestern Yen Bai province on January 2, army spokesman Lieutenant General Vo Van Tuan told AFP.
Later a larger ball weighing some 45 kilograms (100 pounds) landed in a maize field in neighbouring Tuyen Quang province, he said.
“We are still identifying where they came from,” he said, adding the army had determined they did not contain explosives or hazardous material.
The metal balls fell from the sky, he said, scaring local residents.
“Before and after these objects were discovered, the Vietnamese army was not conducting any military activity in the region,” Tuan said.
