"We regret to advise customers that due to an air traffic control strike in France on 2nd June 2016, we have been forced to cancel the flights listed below," Ryanair Ltd., an Irish low-cost airline, said in a statement issued over the flights' cancellation.
The strike, coming ahead of the 2016 UEFA European Championship, which will be held in the French city of Marseilles from June 10 to July 10, has caused the cancellation of over 100 flights in Europe, including 40 flights involving London's Heathrow airport.
Many more airports outside of the United Kingdom are also hit by the French air traffic controllers' strikes.
France is currently facing a series of protests in reaction to the much-discussed labor bill, which has already disrupted work at country's nuclear power plants, refineries, fuel depots, train services and ports.
The labor bill has given a rise to multiple protests across the country in the past months. Among the reforms proposed by Prime Minister Manuel Valls’ government are highly unpopular attempts to increase daily working hours and simplify firing procedures.
