North Korea said overnight Sunday it successfully performed another "crucial test" at its long-range rocket launch site that will further strengthen its nuclear deterrence.
The test - the second at the facility in a week, according to North Korea's Academy of Defense Science - possibly involved technologies to improve intercontinental ballistic missiles that could potentially reach the continental United States.
Pak Jong Chon, chief of the Korean People's Army's general staff, asserted on Saturday that North Korea has built up "tremendous power" and that the findings from the recent tests would be used to develop new weapons to allow the country to "definitely and reliably" counter U.S. nuclear threats.
