Paris, June 15 (RHC)-- At least six demonstrators and 20 policemen were injured as several hundred clashed with police in Paris on Tuesday in the latest demonstration against disputed labor reforms in France. 

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.  France has mobilized up to 90,000 police and private guards to provide security for the month-long tournament.

Authorities made six arrests and at least two people were hurt in the Paris unrest, as demonstrators stormed a building site and began to hurl wooden palettes at riot police.  Photos 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 actions that have seen air and rail transport severely disrupted, fuel shortages and garbage piled up on the streets of Paris.

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.
