Around a dozen museums across the capital have also said they will remain closed on Saturday (Dec. 8) after vandalism and clashes between protesters and police last week rocked France, AFP reported. The announcements came as around 200 high schools across the country remained blocked or disrupted by students protesting a raft of education overhauls, on a fourth day of action called to coincide with the anti-government demonstrations. An interior ministry official told AFP earlier that authorities were bracing for "significant violence" on Saturday, based on indications that protesters on both the far right and far left are planning to converge on the capital. Prime Minister Edouard Philippe told senators Thursday that "exceptional measures" would be taken to avoid the daylong street battles seen last weekend, with 65,000 police deployed across the country. Shops along the Champs-Elysees as well as popular shopping streets near the iconic avenue were told to keep their doors closed, protect exposed windows and remove any outdoor furniture including tables and chairs, according to the police notices seen by AFP. The move is likely to cost businesses thousands of Euros in lost revenue as tourists and locals alike stay clear during a second holiday weekend in a row. The Eiffel Tower said it would stay shut Saturday, and both the Garnier and Bastille opera houses have cancelled performances scheduled for Saturday. Shops are also expected to close in other cities, with officials in Bordeaux, southwest France, already warning that museums, libraries and theaters will remain shut.
