"We've gone as far as we can," says Fabienne Buccio, prefect of the Auvergne-Rhône-Alpes region, the day after a night of clashes and looting in Lyon, the surrounding area and Grenoble. On Saturday evening, the CRS 8, specialising in urban violence, will be deployed in Lyon. The prefect has also announced that she will "try" to send private security guards to "protect" shops, financed by the Chamber of Commerce and Industry. IMAGES AND SOUNDBITES
