Kassel Wilhelmsstr./ Karlsplatz
I don't have any information about the event itself — "Kassel Wilhelmsstr./Karlsplatz" appears to be the name of a tram/bus stop in Kassel, Germany, rather than an event. If you can share details about what's happening (a demonstration, festival, concert, etc.), I'd be happy to write a summary for you.
