Mount Etna on the island of Sicily, in southern Italy, started erupting again at the weekend.

Flames and sparks shot 250 metres into the air and lava poured down the mountain's slopes.

There were concerns that ash from the volcano could block flights out of Catania airport, but winds were blowing the ash away from the airport east towards the Ionian Sea and no flights had been cancelled or delayed.

This is the fourth and the biggest eruption in July, after six months of calm.

Etna is one of the most active volcanos in the world and is the tallest acitive volcano  in Europe.
