South Korea North Korea Sanctions

In Seoul, South Korea, on Sept. 11, 2017, members of Korea Freedom Federation beat balloons symbolizing North Korean weapons during a rally to denounce North Korea's nuclear test. North Korea says it will make the United States pay a heavy price if a proposal Washington is backing to impose the toughest sanctions ever on Pyongyang is approved by the United Nations Security Council this week.
