For the second time, a group of angry taxi drivers have blocked a large road in the heart of Paris to protest ride-sharing apps like Uber.

The BBC reported that the taxi drivers joined with millions of other French public sector workers protesting against labor reforms. At least 20 local taxi drivers were arrested by authorities over their involvement in the protests.

According to the police, they were carrying weapons and started a fire in the middle of the eight-lane road. Police had to use tear gas to control them.

This cluster of protesters were among 1,200 other taxi drivers protesting across Paris, Lille, Marseilles and Toulouse.

Rachid Boudjema, a spokesman for French taxi drivers, commented that Uber drivers “vandalize professionals who are paying taxes, who respect the rules”.
