There was recently a video released on Japanese TV of an execution of several North Koreans in North Korea.
I'm not sure what the story behind the video is, but maybe someone who understands Japanese can give a translation?

The video isn't gruesome, the killings are taped from a distance and the video camera seems to be hidden in the clothes of bystanders.
I think its just a couple of weeks old,
