A cache of explosives, detonators and grenades have been stolen from an army base in the south of France. <br /><br /> The burglary happened despite heightened security in the country after a worker beheaded his boss and tried to blow up an industrial site near Lyon at the end of June.<br /><br /> The high-security army base is located in the town of Miramis around 60 kilometers west of Marseille.<br /><br /> The mayor of Miramis, Frederic Vigouroux, said everything stolen is “inherently dangerous.” <br /><br /> “There is a reinforced double wire fence, we have patrols, there are dogs, every type of security the military can provide. There are munitions, it’s not just a police station,” said Vigouroux<br />.<br />A police official said the burglars appear to have cut through the fence to get into the base. <br /><br /> The Marseille prosecutor said an investigation is underway into charges of “fraudulent entry into a military compound.”
