North Korea confirmed the production of plutonium has been restarted in the country after speculations that it reopened its Yongbyon nuclear facility earlier this month . it will continue conducting nuclear tests till perceived threats from U.S. remain. The Yongbyon reactor was closed down in July 2007. However, North Korean government officials said in September 2015 that theplant was operational again, it was working on improving the “quality and quantity” of its nuclear weapons. Since then, the Kim Jong Un-led country has carried out several nuclear and missile tests, eliciting stricter sanctions from the United Nations Security Council.
