Protesters in Paris threw projectiles at police officers, who responded with tear gas, amid demonstrations on Tuesday by tens of thousands of people opposed to a contested labor reform.
Seven unions and student organizations had called demonstrations against the proposed law to loosen labor rules, which is being debated in the Senate. Protesters set out from southeast Paris heading for the Invalides plaza.
Street protests are planned across France, rail workers and taxi drivers are on strike and the Eiffel Tower was closed on Tuesday because the operators said they could not guarantee public safety.
Taxi drivers temporarily blocked some of Paris' main access roads in the morning.
In a separate protest, Air France pilots are striking to demand better working conditions. About 20 percent of all Air France's flights were canceled, according to the company.
At the Eiffel Tower, an electronic board was indicating "Monument closed - National strike".
Petlev Schultz, a German tourist who came to Paris to attend the European soccer tournament, told the Associated Press: "That's a shame for tourists because we didn't just come for the Euros but also the sightseeing, but we've found out there are strikes everywhere. We are looking into finding way to still experience the beautiful city. "
