Ireland's skies will remain closed to commercial aircraft until at least tomorrow morning, as a volcano in Iceland continues to spew ash up to 11 kilometres into the atmosphere.
Flights at all of the country's airports are affected, with tens of thousands of passengers forced to delay or cancel their journeys.
All commercial flights have been cancelled for the rest of today - with restrictions on air traffic remaining in place until 6am at the earliest.
Prevailing winds are expected to drag the plume of ash across Ireland later, leading to fears that the disruption to air travel could last days.
Within the past hour, Donegal Airport confirmed tonight's Dublin Donegal flight has been cancelled, as has tomorrow morning's Donegal Dublin service. Passengers are advised to contact Aer Arran directly.
Flights from City of Derry Airport are also severely affected - Stephen McNamara from Ryanair says they hope to resume services from Derry and other airports tomorrow - if possible
