Mount Etna began to erupt on Sunday, dumping black ash over vehicles and runways.
The video shows a smoggy cloud covering the roads, and dark flakes of ash on car windscreens.
The airport announced on Twitter that flights in and out Catania on Sicily’s East Coast are suspended until Monday at 9am local time, or until it can guarantee safe conditions.
Europe’s most-active volcano can wake up several times per year and jettison ash and lava high above the Mediterranean island.
It hasn’t erupted in a major way since 1922.
Cloud cover and rain on a rainy day obscured views of the eruption. This is according to Italy’s National Institute of Geophysics and Volcanology, which monitors Etna closely with instruments on its slopes.
Ash had been reported to have fallen in Catania, and at least one other town situated lower down on the slopes of this 3,330-metre high volcano.
The INGV reported that recent monitoring evidence had shown an increase in tremor activity.
