French anti-capitalist activists clashed with riot police at burning barricades Monday during a huge security operation to clear a rural protest camp at the site of an abandoned airport project in western France. Some 2,500 police were deployed to raze the decade-old camp at Notre-Dame-des-Landes near Nantes, and evict the last of the protesters who had refused to leave despite the government agreeing to ditch the proposed airport. The activists used tractors and burning barricades of tires, wooden pallets, hay bales and electricity poles to try to keep the police at bay. AFP pictures showed flames and plumes of black smoke rising into the air as columns of helmeted officers with gas masks and shields clashed with hooded activists. The police fired tear gas to disperse dozens of protesters who threw petrol bombs, rocks and flares, injuring one officer in the eye, according to the interior ministry. In January, the government jettisoned plans for an airport at Notre-Dames-des-Landes that had divided the local community for nearly half a century, and told the protesters to clear off the farmland by spring. But some of the motley group of eco-warriors, anti-capitalists and farmers who had turned the 1,600-hectare (4,000-acre) site into a utopian experiment in autonomous living had demanded the right to stay put. The government said the main aim of the operation was to retake control of a key road that had been blocked for five years and evict around 100 "of the most radical" squatters from a total of around 250. In a statement, the protesters expressed anger over the destruction of their huts and shelters, vowing "We will not leave". By mid-morning some 10 shelters had been demolished out of a target of around 40, along with a watchtower erected by the activists to guard their terrain, regional security official Nicole Klein told reporters.  The activists moved onto the site in 2008 and have since built up a community they bill as a model of sustainable farming and political debate that they have tried to replicate in other parts of France.
