WASHINGTON (Reuters) - Satellite imagery of North Korea's main nuclear test site taken over the weekend indicates that Pyongyang could be in the final stages of preparations for a sixth nuclear test, a U.S. think tank reported on Tuesday.

Washington-based 38 North, a website that monitors North Korea, said the images from Saturday showed the continued presence of vehicles and trailers at the Punggye-ri test site and signs that communications cables may have been laid to a test tunnel.
