The Icelandic Civil Aviation Authority (CAA) has announced that two airports, Keflavik International Airport and Reykjavík International Airport, will be closed from today until further notice, due to volcanic ash cloud following the recent volcano eruption.
The country said it is considering the change in wind direction that began blowing ash east towards Iceland's capital and its airport.
This is the first time that Iceland has had to close its own airports, a week after ash from an Icelandic volcano forced the shutdown of European airspace and stranded thousands of passengers around the world.
The aviation authority said two other Icelandic international airports, Akureyri Airport and Egilsstadir Airport, will stay open and function normally.
Icelandair said transatlantic passengers from the US and Europe stopping in Keflavik will be rerouted via Glasgow, Scotland.
Passengers travelling to and from Iceland will have the option of being re-routed through the Akureyri airport.
In Europe, most airports remained open on Thursday and will resume normal operations on Friday, however airports in northern Scotland were also closed.
