South Korea's presidential office has convened a standing committee of the National Security Council(NSC) in response to North Korea's firing of a suspected intercontinental ballistic missile(ICBM) into the East Sea on Monday.

A briefing by the Joint Chiefs of Staff(JCS) starting at 10:30 a.m. is set to precede discussions on response measures, with no confirmation on who will preside over the meeting.

Earlier the JCS announced that the North fired a suspected long-range ballistic missile from Pyongyang into the East Sea at around 8:24 a.m.

Late Sunday, Pyongyang fired a short-range ballistic missile that the JCS determined flew 570 kilometers before falling into the East Sea.
