New satellite images revealing an underground tunnel indicate North Korea may be preparing for another nuclear test, its third thus far, according to the Associated Press.
The AP acquired an intelligence report that states that "North Korea is covertly preparing for a third nuclear test, which would be another grave provocation," and cites satellite images taken on April 1. The tunnel found in the images has dirt piled at its opening, which experts say is one of the last steps in preparing a tunnel for a nuclear test and suggests there is a "high possibility" of a test in the future.
The news comes as North Korea is preparing for a long-range rocket launch in honor of the 100th anniversary of the birth of the founder of North Korea, Kim Il Sung. International officials believe the rocket launch may be a test of missile capabilities that could be used to fire on the United States.
