In the night between July 9th and 10th a bureau of the AfD (Alternative for Germany) in Jena, Thuringia, got destroyed and covered with white dust, probably a work by the homecoming Antifa who just attend G20.

Thuringia is famous for its funding of left wing groups, even giving money to the "Reisegruppe Antifa" (Travel group antifa).

The extreme left sees them as racists, homophobics and sometimes even fascists and tries to prevent political work of the AfD.
