North Korea has made a nuclear bomb lighter and achieved its "standardization," the communist country's state television said Wednesday, in the latest claim that it has made strides in its weapons capabilities.
The North's official Korean Central Television said Kim Jong-un made the remarks at a meeting with scientists and technicians, where he gave his guidance on the development of nuclear weapons.
"It is a very great warhead that is designed in a reasonable structure that enables an instantaneous thermonuclear reaction using our own style of mixed explosives," he was quoted by the state media as saying.
Complementing nuclear scientists and technicians, Kim also said that they have made a "tremendous" achievement in the defense science project.
A week ago, the U.N. Security Council adopted a new sanctions resolution punishing the North for its Jan. 6 nuclear test and Feb. 7 long-range rocket launch.
Pyongyang has already claimed it has entered a technological phase to miniaturize and diversify nuclear bombs. (Yonhap)
