Angry French farmers are calling for more protests over the government-backed slaughter of cattle herds affected by so-called Lumpy Skin Disease (LSD).
On Thursday there were clashes between riot police and demonstrators in the southern Ariège department, after vets were called in to destroy potentially contaminated cattle at a farm.
Elsewhere in the south, farmers have dumped manure outside government buildings and blocked roads. The offices of several environmentalist groups were ransacked in the Charente-Maritime department.
LSD is a highly contagious bovine disease which is transmitted mainly by fly-bites. The symptoms are fever, mucal discharge and nodules on the skin.
Though mainly non-fatal, it can badly affect milk-production and the cows are unsaleable.
