French newspapers don’t mention any of those for now, the only mention is that the methodology is similar to previous far-left activism (source: lemonde.fr/…/en-direct-attaque-massive-contre-la-…), which could be a disguise of course.

It could also be both, local activists helped by foreign influence, willingly or not.
