Ryanair has suspended all flights to and from Ukraine for the next two weeks after Russia launched a full-scale invasion overnight.
The budget airline is one of the largest operators in Ukraine.
Plans had been in place to base upwards of twenty planes in Ukraine in the next couple of years.
Customers also won't be able to purchase a ticket to Ukraine for the next four weeks after the airline removed Ukrainian destinations from being sold online.
Ryanair previously flew to Ukrainian capital Kiev from Dublin Airport.
The airline said: "Due to the closure of Ukrainian airspace overnight and the apparent invasion by Russian forces, all Ryanair flights to/from Ukraine have been suspended for at least the next 14 days."
"All affected passengers will receive email notices later this morning and all flights to/from Ukraine have been removed from sale for at least the next four weeks until further information becomes available from EU safety agencies."
"Ryanair remains committed to our services to/from Ukraine and we look forward to restoring flight services there as soon as it is safe to do so."
"We sincerely regret and apologise for these unprecedented disruptions and any inconvenience that they will inevitably cause to our Ukrainian customers."
