K-pop star Sowon has apologised after posing with a mannequin wearing Nazi clothing and posting the images online.

The photos show Sowon, a member of GFriend, cuddling the mannequin, and were taken in a café last November while the group were filming a video.

They have since been deleted from her Instagram. Her management said she felt a "profound sense of responsibility" over posting the images.

Many people took to social media to call for the star to apologise.

Source Music, her management company, said in a statement to CNN, external that she was shocked and deleted the post "when she understood the significance of the image".

It is common practice for K-pop singers to issue apologies through their management.
