UNITED NATIONS – South Korea is urging the international community to make a united effort against North Korea's nuclear program, as it has against the use of chemical weapons in Syria.
Foreign Minister Yun Byung-se on Friday told the U.N. General Assembly that North Korea launched long-range missiles and conducted a nuclear test this year in "blatant violation" of Security Council resolutions.
Yun says nations should work together "to prevent the advent of another nuclear-armed state."
He also criticizes the North's "inhumane" decision to postpone planned reunions of families separated by the 1950-53 Korean War that were due to happen this week.
The reunions had been seen as a sign of reduced tensions.
Yun says South Korea stands ready to help North Korea if it changes its ways.
North Korea speaks next week.
