Italy's Mount Etna on the island of Sicily erupted Monday, spewing ash and hot lava that sent tourists fleeing from the 10,925-foot mountain, which is one of the world's most active volcanoes.

Mount Etna is Europe’s largest active volcano and has erupted at least once per year for the last several years.
