Iceland volcano: Bardarbunga eruption sparks red travel alert
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.
Geophysicist Dr Ian Stimpson told the BBC that so far it looked unlikely to cause the disruption to air travel that Iceland's Eyjafjallajokull volcano caused in 2010, but melting ice could trigger bigger eruptions.
