The Irish Aviation Authority has decided to close Irish airspace as coverage from the ash cloud from the volcanic eruption in Iceland worsens.
The ban lasts until 1800 Irish time (13 00 ET).
“'The ash from the volcano is now being emitted to a higher level and thus the area of coverage and risk to aircraft has increased," said the IAA in a statement.
“Based on the latest reports the Irish Aviation Authority has closed Irish Airspace from 0600 to 1800 hours today Saturday 17th April.
“No commercial passenger flights including North American traffic will operate from any Irish airport during this period.”
