North Korea vowed on Saturday to boost its "nuclear power" to counter Washington's hostile policy, saying it had become apparent the United States aimed to invade the North under the guise of human rights abuses.
"Now that the US hostile policy with an aim to invade our republic under the guise of human rights has become apparent, the idea of denuclearizing the Korean peninsula itself is no longer valid," the North Korea's foreign ministry spokesman said on KCNA, NBC News reported.
"Our effort to strengthen our defensive military power including nuclear power will be doubly stepped up in every way," the spokesman added.
