Iceland has issued a red alert to the aviation industry for the Bardarbunga volcano, meaning significant ash emissions are likely.
The Icelandic Met Office has warned that a small eruption under an ice cap has begun at Bardarbunga.
The air space over the site has been closed, but all Icelandic airports currently remain open, authorities say.
