North Korea conducted its third underground nuclear test today, three weeks after the United Nations increased sanctions against Kim Jong Un’s regime following its December long-range rocket and satellite launch.
North Korea detonated “an atomic warhead that is lighter and miniaturized but with a big explosive charge,” the official Korean Central News Agency said today. South Korea said the nuclear explosion took place at 11:57 a.m. local time with an estimated yield of 6 to 7 kilotons, bigger than North Korea’s previous tests in 2006 and 2009.
The UN strengthened sanctions against North Korea after it launched an Unha-3 long-range rocket in December. The North began developing ballistic missiles in the 1970s and its current arsenal of operational weapons includes Musudan rockets, which may be able to carry a 650 kilogram (1,430 pound) warhead as far as 3,000 kilometers (1,860 miles), according to South Korea’s Defense Ministry.
