BERLIN (AP) — A descendant of an executed opponent of the Nazis tried to remove a wreath from the far-right Alternative for Germany party at an event in Berlin marking the 82nd anniversary of a failed attempt to kill Nazi dictator Adolf Hitler.

Tobias Korenke, a great-nephew of Protestant pastor and theologian Dietrich Bonhoeffer, attempted to remove the wreath from the parliamentary group of Alternative for Germany, or AfD, at Monday’s event at the site where the main plotters were executed, German news agency dpa reported. Security officers intervened, and the wreath was damaged in the scuffle.
