Lava flows from the Mount Etna volcano on the southern Italian island of Sicily, near Catania, late on December 6, 2015.
The volcano on the Mediterranean island threw up an ash column some seven kilometres (4.3 miles) high with lava flowing from the Voragine crater for the first time in two years, the National Institute of Geophysics and Vulcanology (INGV) said. The eruption, which began on December 3, 2015, is among the most &quot;energetic of the past 20 years,&quot; added the INGV.  / AFP PHOTO / GIOVANNI ISOLINO
