Secretary-General Ban Ki-moon is warning North Korea against "further provocative measures."
The U.N. chief was asked to comment on Monday's warning from North Korea's military of imminent "special actions" that would reduce South Korea's government to ashes within minutes. North Korea attempted to launch a rocket on April 13 but it disintegrated.
Ban urged North Korea to fully observe U.N. Security Council resolutions which reflect the will of the international community. The resolutions imposed tough sanctions against the North and ban nuclear and missile tests.
Ban, a former South Korean foreign minister, said "any further provocative measures will not be desirable for the peace and stability of the Korean Peninsula."
