Demonstrations have been held in different cities of the country since March 16, when French President Emmanuel Macron took the step to implement the pension reform, which was his election promise, without a vote in the government parliament.
The demonstrations sparked tense moments between the protesters and the police, who demanded that the government abandon the reform.
According to local media data, the number of people detained since Thursday has exceeded 500.
While 283 of the demonstrators were released, 9 of them were brought before the prosecutor.
The ban on holding demonstrations in the square close to the parliament in Paris continued today.
On the other hand, the windows of the office of center-right Republicans (LR) party chairman and deputy Eric Ciotti in Nice were smashed.
Ciotti had announced that his political group would not vote for no-confidence motions against the government.
The opponents of the reform started to organize demonstrations after Prime Minister Elisabeth Borne tried to put the regulation into effect by using the 3rd paragraph of the 49th article of the Constitution without putting it to a vote in the parliament on 16 March.
