French Prime Minister Francois Fillon has warned that hundreds of workers at the Continental tyre company who trashed a government building on Tuesday to protest planned layoffs should face charges, calling their acts "unacceptable".

AFP - Prime Minister Francois Fillon warned Wednesday that workers who vented their anger by trashing a government building should face charges, as fears grew of French labour unrest turning violent.
   
Workers from the German-owned Continental tyre company went on a rampage Tuesday after a court refused to block the company's decision to shut down their factory and scrap 1,200 jobs.
   
A few hundred employees ransacked offices of the regional administration in Compiegne, northeast of Paris, smashing windows, overturning desks and wrecking computers.
