Watch: Mount Etna puffs 'smoke rings' in rare display
Italy's Mount Etna has been putting on a show by blowing near-perfect circles into the Sicilian sky.
A new crater opened on the summit of Europe's largest active volcano leading to an unusual display of the so-called 'smoke rings'.
The rings are made of gases and propelled by a circular vent in the volcano.
