Iceland’s erupting volcano is once again causing travel disruption to airlines.
Aviation authority Eurocontrol said a potentially dangerous concentration of ash had forced it to divert several transatlantic flights.
Scientists say Eyjafjallajokull has shown increased activity in recent days, although the current particle plume is lying in the north Atlantic, west of Ireland and the British Isles.
For the moment that is limiting the travel turmoil but the latest scientific data eruptions will be of concern to airlines and authorities.
Earlier this week, volcanic eruptions from Iceland shot up as high as ten kilometres causing considerable travel chaos in Ireland and Scotland.
However, it was nothing on the scale of April, which ground flights across Europe for almost a week.
