PARIS, Nov. 9 (Xinhuanet) -- France's rioting seemed to calm down a bit during the 13th consecutive night of unrest, with fewer towns affected and fewer cars burned down by local manic youths, police said Wednesday.

    During the night from Tuesday to Wednesday, more than 600 cars were burnt and 116 towns wrecked. Though still big, the numbers are just half of the figures of the previous night.

    The night earlier, 1,173 vehicles were set ablaze and 226 towns affected, national police spokesman Patrick Hamon told a news conference on Wednesday. More than 130 people had been arrested by early Wednesday.

    French Prime Minister Dominique de Villepin invoked a 1955 law on state of emergency in a bid to stamp out the unrest, and several towns imposed a curfew as from midnight. The measures seem to be taking effect as the number of violent incidents dropped sharply overnight.

    French officials are concerned over investment and tourism that were hit hard by the violence.

    The Violence has raged through France since Oct. 27, which began in Clichy-sous-bois, northeast of Paris. It was triggered after two teenagers were accidentally electrocuted while hiding inan electrical sub-station to flee a police identity check. Enditem
