Low-cost airline Ryanair has confirmed that 30 flights to and from Ireland and the UK will be cancelled Thursday following the breakdown of talks between the company's management and its unions.

The airline has also announced that it "expects limited disruption" as well as the flight cancellations.

Ryanair pilots have been on a 24-hour strike since 1am UK time Thursday.

The airline has said that only flights to and from Ireland to the UK are affected.

Ryanair met with union officials on Wednesday for talks which did not reach any agreement after seven hours.

The pilots' union Fórsa, which includes the Irish Airline Pilots's Association (IALPA) had earlier said it was not optimistic that a deal could be reached to avert the strike.

Flights between Ireland and Europe are supposed to operate as usual.

"All customers who are travelling on flights to/from Ireland on Thursday 12 July who have not received any email or text notifications of flight cancellations should travel to their departure airport as normal," Ryanair said in a statement.
