Foreign Minister Yun Byung-se left Seoul on Thursday to attend a special minister-level meeting on North Korea's nuclear weapons programs at the United Nations Security Council.

He told reporters at Incheon International Airport that it remains possible the North will engage in provocative activity during the month of April.

Yun noted that this is the first time the UN Security Council is holding a minister-level meeting solely dedicated to North Korea, showing how serious the international community takes the nuclear issue.

U.S. Secretary of State Rex Tillerson, this month's chair of the council, is set to preside over the meeting of 15 member states Friday in New York.
