Around 800,000 reportedly took part in a nationwide strike that is deemed to be the largest in decades. Footage from Paris shows streets covered in smoke, with protesters flooding the French capital.
One of the firefighters taking part in the strike said that protesters have been "annoyed" for six months.
One of the locals, in turn, condemned the demonstration that saw a rubbish bin set on fire as well as rocks hurled at gates of one of the businesses. "It is not putting a trash bin on fire that is going to help to reform retirement pension. This was our private trash bin and this is impossible to stop it from burning. For the record a trash bin is burning for a long time," he said.
People were outraged by French President Emmanuel Macron's pension reform plans.
