Spectacular pictures have been captured of a lightning display over Iceland's Eyjafjallajoekull volcano which continues to erupt.
Hundreds of thousands of people have been stranded across the globe as a result of the eruption which has shut down the airspace across Europe for the fifth day in a row.
More than 25,000 flights have so far been grounded in what has been billed as the single biggest aviation incident since the Second World War.
