Five protesters and a police officer were injured during a mobilisation against irrigation reservoirs being built on France's Atlantic coast, reports Yahoo! News.
Critics of the massive infrastructure projects say that they will benefit larger agricultural producers at the expense of small farmers.
Environmental protesters clashed with police in France's western port of La Rochelle Saturday, AFP journalists saw, as conservationists and small farmers mobilised against massive irrigation reservoirs under construction.
A 2,000-strong march, one of two through the city, was turned back and broke up at around 2:00 pm (1200 GMT) after being charged by police.
Running battles erupted around barricades and burning rubbish bins as some threw projectiles and police fired tear gas grenades.
"We were in the demo, they started blocking ahead and behind. They isolated us off to one side to charge everyone else," said Lilia, a 25-year-old who declined to give her second name.
