A French police officer was reportedly injured Monday as 2,500 cops swarmed a protest camp occupied by eco-activists and anarchists, who pelted police with stones, gasoline bombs and flares.
The National Gendarmerie police service said the officer was hospitalized after being hit in the eye with a flare, but was not in life-threatening condition.
At least one person was arrested and scattered clashes occurred as police moved into the site in Notre-Dame-des-Landes in western France.
The site in Notre-Dame-des-Landes has been filled for years with squatters who were opposed to a plan for a $750 million airport the French government ultimately scrapped in January, according to Reuters.
Many of the squatters stayed in place, and sought to turn the area into a "space of social, environmental and agricultural experimentation."
The gendarme service said about 100 squatters were living at the site when Monday's operation began, and a few hundred others came to join Monday's protests.
Authorities had blocked surrounding roads starting at 3:30 a.m. local time before beginning the operation at 6 a.m. -- when a Reuters journalist saw protesters set fire to the barricades.
France's Interior Ministry said in a statement the police operation was to "put an end to a lawless zone."
“Illegal constructions must be brought down for things to come back to normal in Notre-Dame-des-Landes,” Interior Minister Gerard Collomb told Europe 1 radio.
Proponents had argued the region needed a larger airport to boost its economic prospects, while those opposed to the project said a new airport was unnecessary and a symbol of exploitative globalization.
The government requisitioned the land from farmers for the airport, but is now offering to return the land to those who want it.
