Mount Etna erupts in Sicily amid dozens of tremors
Europe's most active volcano, Mount Etna in Sicily, erupted on Monday, with officials reporting more than 130 earthquakes of up to 4.3 in magnitude.
The Mount Etna observatory said lava had spewed from a new fracture near its south-eastern crater, BBC reports.
A local volcanologist said it was Etna's "first flank eruption" in more than a decade.
Volcanic ash covered nearby villages, while planes into Catania airport had to be halted temporarily.
A large explosion was felt close to Etna during the morning.
A video filmed 2,500m (8,200 ft) up the 3,350m volcano showed the fast spread of ash. People on the mountainside were told to escape quickly.
Catania airport said later that the airspace had been reopened to allow four planes to land per hour, before confirming it would return to normal operation by 20:00 local time (19:00 GMT).
Although Etna has seen frequent eruptions, the INGV said in August that the volcano had grown faster than ever before in recent years.
