 "Clashes break out in the stands after the Euro 2016 Group B soccer match between England and Russia at the Velodrome stadium in Marseille, France")
Several hundred masked protesters hurled objects at police in Paris, on Tuesday, as the latest demonstration against disputed labour reforms in France descended into violence.
The clashes erupted as the international spotlight was turned on France as the host of the Euro 2016 football championships, which have also been marred by violence between fans.
Strikes closed the Eiffel Tower and disrupted transport links as tens of thousands of fans pour into the country for Europe's showcase football event.
Authorities made six arrests and at least two people were hurt in the Paris unrest, according to an AFP reporter at the scene, as demonstrators stormed a building site and began to hurl wooden palettes at riot police.
Pictures showed one man being led away by officers in riot gear with blood streaming from a wound above his eye, his white T-shirt splattered with blood.
The strike is the latest in months of industrial action that has seen air and rail transport severely disrupted, fuel shortages and rubbish piled up on the streets of Paris.
"I've been to all the demos since March because I want to live in dignity, not just survive," said Aurelien Boukelmoune, a 26-year-old technician marching in Paris.
"I want the reforms to be withdrawn, pure and simple. Only then will it stop. For the government's sake, they should withdraw the law, otherwise we'll block the economy."
With France on high alert due to the threat of terrorism during Euro 2016, overstretched security authorities feared the demonstrations could turn violent and banned 130 known troublemakers from taking part.
The terrorism threat was thrust back into the spotlight after a man claiming allegiance to Islamic State jihadists killed a policeman and his partner at their home in a northwestern Paris suburb late Monday.
The latest in a wave of protests that began in March coincides with a French Senate debate on the reforms, which are aimed at making the job market more flexible and reducing high unemployment but which critics see as too pro-business.
President Francois Hollande's Socialist government has voiced hope the latest day of protest will be a last stand for the movement.
But Philippe Martinez, head of the far-left CGT union that spearheaded last month's blockades of fuel depots and an ongoing rail strike, predicted a "very strong mobilisation".
The CGT laid on more than 600 buses to transport demonstrators to Paris and said it hoped to attract more support than in March, when it claimed 1.2 million people took to the streets.
Authorities put the March figure at 390,000.
For today's protest, Paris police chief Michel Cadot said he expected "maybe more than 50,000 demonstrators" in the capital alone.
Two further protest days are set for later this month.
