North Korea said the world will have to "wait and see" for details about its "new form" of nuclear test, the country's government officials announced on Friday.
The nuclear test is the Democratic People's Republic of Korea's response to remonstrations from the United Nations over its recent string of missile launches, Reuters reported.
"The DPRK made it very clear, we will carry out a new form of nuclear test," Ri Tong II, North Korea's deputy U.N. ambassador, said at a news conference on Friday, Reuters reported. "But I recommend you wait and see what it is," the ambassador added.
Friday's U.N. conference was the third one held by North Korea so far this year.
The U.N.'s Security Council said on March 27 that it will form an "appropriate response" after North Korea fired two Rodong ballistic missiles into the ocean the day before. The medium-range missiles have the potential to reach Japan, Reuters reported.
The Security Council already has sanctions in place aimed at restricting North Korea's missile launches and nuclear program. Ballistic missile launches are banned, as well as the exporting of luxury goods to the country, Reuters reported.
The sanctions became stricter after Pyongyang carried out an atomic test in 2013, its third one since 2006.
North Korea has accused the U.S. of ignoring proposals from the country on denuclearizing the Korean peninsula because the U.S. wants its military presence to remain, Reuters reported.
"The U.S. is hell bent on eliminating the DPRK politically, isolating DPRK economically and annihilating the DPRK militarily," Ri said, Reuters reported. "There is a great question mark why the U.S. is hell bent on increasing the tension, ignoring the DPRK proposals, very important for peace and security."
Reuters' request for comment from the U.S mission to the U.N. on Ri's statements was not immediately answered.
