A photo of mostly white US students laughing as they make a Nazi salute has triggered outrage.
More than 50 boys from Baraboo High School in Wisconsin were pictured making the “Sieg Heil” gesture.
The school district and local police have launched an investigation into the image, which was reportedly snapped before a junior prom.
The Auschwitz-Birkenau Memorial and Museum condemned the photo.
One of the boys in the picture made an OK sign with his thumb and forefinger, a gesture that has been adopted by white power groups.
An anonymous Twitter account reportedly run by students at the school shared the photo, saying: “We even got the black kid to throw it up.”
One non-white student appears in the picture, though he is partly obscured.
