A large metal object thought to be from a rocket fell from the sky onto a jade mine in Myanmar.
Nearby villagers said their houses “shook” as the cylindrical object crashed and skidded over the ground.
Measuring 4.5 metres long by 1.2 metres wide, it was found on Thursday in the northern Kachin state.
The incident has been linked to the launch of a Chinese satellite from a rocket at the Juiquan Satellite Launch Centre the day before.
A second piece of metal with Chinese writing on it broke through the roof of a nearby house at the same time, although nobody was reported injured.
Local residents told of a loud bang as the object landed and bounced a reported 50 metres.
Villager Ko Maung Myo told the Myanmar Times: “We were all afraid of that explosion. Initially, we thought it was a battle. The explosion made our houses shake. We saw the smoke from our village.”
A local newspaper, Global New Light, said: “The metal objects are assumed to be part of a satellite or the engine parts of a plane or missile”.
Pieces of rockets are designed to drop away into bodies of water or large, safe, uninhabited areas.
The Kachin state government said it could not immediately identify the object.
