The unidentified flying object is NOT believed to be a plane as none have been reported missing in the area.
Investigators are working on the theory the explosion happened five miles above the ground.
A search of Phu Quoc island off southern Vietnam uncovered shards of grey “metal” up to four feet long.
Unexplained explosion … map showing island
Soldiers combed the area for clues yesterday as airlines in Vietnam, Cambodia and Thailand insisted none of their aircraft were missing in the area.
Villagers in the nearby Cambodian province of Kampot said on Tuesday that they had heard a loud explosion.
A day later they found chunks of material near the coastline.
After the explosion Kung Mony, of Cambodia’s Air Force, claimed it could have been a foreign plane but he later backed down from the theory. One explanation could be that the plane was a military one – but none of the nearby countries has admitted to losing any aircraft.

Villagers say they heard a loud blast yesterday and later found shards of metal near the island’s coastline.
The sensational revelations come one day after neighbouring Cambodia’s air force retracted a report of a mysterious plane crash.
The Vietnam News Agency said residents of Phu Quoc island, six miles off the coast of the Cambodian province of Kampot, found shards of grey metal, including one 1.5metres long.
“The explosion happened at about five miles above the ground, and perhaps it was a plane, but authorities could not identify whether it was a civil or military aircraft,” the VNA claimed.
The official state news agency added that soldiers were sent out to look for the wreckage and survivors, and local authorities contacted airlines in Vietnam, Cambodia and Thailand, but received no reports of missing aircraft.
Villagers in Kampot also said they heard a loud explosion yesterday and today found small chunks of metal near their coast.
Kung Mony, deputy commander of Cambodia’s Air Force, yesterday said he had been told of a foreign plane crashing in Kampot province, but later backed off his claims of an aircraft accident.
