Police fire teargas in Paris and Limoges town hall ‘largely lost’ to fire – with officials blaming violence on ‘ultra-left’

More than 1,800 people were arrested in France on Saturday after protesters supporting high school students clashed with police, with some demonstrations later spiralling out of control as buildings were set ablaze and shops looted.

Police fired teargas in confrontations with protesters, as demonstrations across France were boosted by other groups angry about high prices and the fraying of a social welfare system. While hundreds of thousands protested peacefully in street marches in scores of cities, violent fringe groups targeted public buildings, luxury boutiques and supermarkets and attacked police vehicles and officers.

Whether it was youngsters proving their skills or state sabotage, Europe’s most hacked country was left with a mountain of waste after food began cooking in freezers

Shortly before midnight last Sunday, the digital thermostats controlling hundreds of supermarket cold aisles across France began to flicker and rise.
