A popular teenage all-girl band in Japan is under fire for performing in outfits resembling Nazi-era German military uniforms.

The members of Keyakizaka46 appeared recently in black knee-length dresses that look like military overcoats, and black capes and officer caps with a Nazi-like eagle emblem.

The US-based Simon Wiesenthal Center issued a statement on Monday saying it was disgusted by the uniforms and calling on the group's label, Sony Music, and its producer to apologize. The center is a human rights group focused on anti-Semitism and hate speech.
