In a new wave of violent action, winegrowers from the Languedoc-Roussillon region were behind a series of explosions in Montpellier and Carcassonne late on Thursday evening/early Friday morning.

The explosions were caused by sticks of dynamite being thrown at the entrances to state buildings. A car was also set on fire. No one was hurt but material damage was reported.

The latest incidents in a run of wine-industry related violence have been severely condemned by official winegrowers associations who blame them on a breakaway protest group, CRAV, who in the past week have also carried out acts of vandalism at supermarket chains, the latter viewed as being responsible for the fall in wine prices

Official growers groups have called for a new demo on 20 April in Narbonne.
