Protesting prison guards have clashed with police outside the sprawling Fleury-Merogis prison near Paris.<br /><br /> Things came to a head after a few hundred guards blocked the entrance and set tyres on fire to call attention to concerns about security and overcrowding.<br /><br /> Police sought to dislodge them from the blockade but met resistance and fired tear gas to try to disperse the crowd.<br /><br /> The prison which is used for housing violent criminals and Islamist extremists is working on a 190 percent capacity with what the unions say are too few prison guards.<br /><br /> Six were recently attacked prompting the latest protest.<br />
