Tensions rise in Erfurt as thousands protest against the AfD party congress this weekend.

In Erfurt, demonstrators have taken over a central square, blocking traffic and disrupting public transport. Over 200 buses filled with anti-AfD protesters have arrived, with police reporting significant disruptions to the tram services.

The police are on high alert, expecting up to 2,500 violent left-wing extremists. Meanwhile, the AfD prepares to re-elect its leadership at the congress, with security measures in place to ensure the event proceeds smoothly despite the protests.
