A leading Jewish human rights group has denounced popular K-pop band BTS, whose live performance on Japanese TV was canceled last week, over a T-shirt mocking victims of the atomic bombing of Japan while also claiming that a photo shoot had shown them wearing hats with a Nazi logo.

The Los Angeles-based Simon Wiesenthal Center blasted BTS in a statement released Sunday.

"Wearing a T-shirt in Japan mocking the victims of the Nagasaki A-bomb, is just the latest incident of this band mocking the past," Rabbi Abraham Cooper, associate dean and director of global social action with the center, said in a statement.
