A mysterious cylinder has fallen on a tiny village in Siberia, causing widespread speculation as to what it is.
Russian media have identified it as a piece of space debris, while others say it is the fuel tank of a ballistic rocket.
Tests show that the object is not radioactive, and it appears to be made of a titanium alloy.
The Russian Federal Space Agency has denied ownership of the cylinder.
“The object is not a rocket or a spacecraft, but final conclusions can only be drawn once it is examined,” said an agency statement.
