Sicily's Catania airport on Wednesday suspended flights until at least 4 p.m. local time (1400 GMT/UTC) on Thursday, responding to fresh ash emissions from Mount Etna.

The volcanic ash can pose a danger to aircraft and so has forced regulators to restrict access to the airspace around eastern Sicily, disrupting the peak summer holiday season.

Where were flights affected?

"Passengers are advised to check the status of their flights with their airlines," airport operator SAC said. "Further updates will follow in the coming hours."

Travel disruptions have impacted eastern Sicily in particular since last Friday, when renewed rumblings from Europe's most active volcano and shifting winds started carrying ash over the region. The airspace was fully closed only in recent days as the eruption continued.
