An activist group has apologized to Jewish organizations outraged over their use of purported Holocaust victims’ remains in an installation outside Germany’s parliament building meant to draw attention to the perils of far-right extremism. The Center for Political Beauty, a Germany-based activist group known for provocative stunts, installed an urn outside the Reichtstag building on Monday, saying it contained victims’ remains that it had unearthed from 23 locations near Nazi death and concentration camps in Germany, Poland and Ukraine. Following the uproar from Jewish organizations decrying the stunt as an instrumentalization of the Holocaust and an affront to the dead, the group apologized and by Thursday morning the urn had been wrapped in opaque black plastic so its contents could not be seen.
