Following last week's demonstration in Nimes, Languedoc-Roussillon winemakers have continued their action in a violent manner.

Photos in the French press last week showed a masked individual from the militant group of growers, CRAV (Comite Regional d'Action Viticole) emptying a vat of Chilean wine worth €500,000 at a trader's premises at Montferrier, north of Montpellier.

A coach-load of protesters, meanwhile, has carried out a number of commando-style raids at discount supermarkets selling foreign wine before being intercepted by riot police. The protesters were found to be in possession of clubs, iron bars, hoods and gas masks.

Damage estimated at €1m was also done to a railway branch line.
