Italy's Mount Etna, the tallest volcano in Europe, erupted on Sunday for the fourth time this year.
A massive plume was reportedly seen rising as high as seven kilometres from Mount Etna off the Italian island of Sicily.
The volcano erupts often but has not caused any damage. Nearby airports remained open and continued operations during the eruption although authorities shut down two nearby flight paths, reported the Telegraph.
Mount Etna is one of the most active volcanoes in the world, which started erupting several million years ago.
