Angry protests against Uber have sparked travel chaos in Paris as French taxi drivers launched a nationwide strike against the popular US-based ridesharing service.

A number of violent incidents erupted during Thursdays protests, which follow weeks of rising opposition to the taxi app.

The BBC reports that taxi drivers blocked the roads to the French capital’s airports and the peripherique, the main ring road around the city, building blockades and burning tires. Blockades were also set up in the southern French cities of Marseille and Aix-en-Provence, it reported.

As a result of the strike, Aeroports de Paris urged passengers to use public transport when travelling to the city’s airports of Charles de Gaulle and Orly. “Taxi drivers strike: blocked road access. Come to the airport by RER B,” it posted on its website, referring to the train connecting Charles de Gaulle and Orly to the center of Paris.

Tweets from musician Courtney Love Cobain strongly suggested that she was caught up in the Paris violence Thursday. Love Cobain tweeted that her taxi was “ambushed” and added that protesters were “beating the cars with metal bats.”
