U.S. spy satellites have detected suspicious activity at North Korea's underground nuclear test site in Punggye-ri, North Hamgyong Province, CNN reported Tuesday.
Citing U.S. government officials, CNN said the activity "appears to involve some modifications around one of the tunnel entrances."
The officials said it is "not yet clear if the activity indicates a sixth nuclear test is imminent, but noted there is concern that North Korea could set off a test during Wednesday's visit to Washington by top Chinese diplomats and military officials," CNN said.
U.S. authorities believe North Korea has already made preparations for a nuclear test at any time in Punggye-ri. The website 38 North at Johns Hopkins University said water has been spotted pouring out of a tunnel in the northern part of the complex where test preparations appear to be in progress, while two trucks were also spotted parked near the engineering wing.
The website, whose conclusions are usually reliable, concluded that the complex is in "stand-by mode" ahead of a nuclear test.
