Tempers flared in Paris as striking taxi drivers blocked key roads and set fire to tyres on a "black Tuesday" that saw simultaneous strikes by air traffic controllers, civil servants, hospital workers and teachers, AFP reports.
At Orly airport, one protester was injured in the leg when a shuttle bus forced its way through a blockade. Police said the bus driver was arrested.
Some 300 taxi drivers furious over competition from non-licensed private hire cabs also blocked the capital's ring road at a key intersection in the west of the city, lighting fires and throwing smoke bombs.
"Today our survival is at stake, we are fed up of meetings and negotiations," said Ibrahima Sylla, spokesman of the Taxis de France collective.
Nineteen protesters were arrested, police said.
