There are concerns that North Korea will conduct a nuclear test as soon as Wednesday.
The South Korean government had said Sunday that it believes North Korea may test a missile about April 10, citing as an indicator Pyongyang’s push for workers to leave the Kaesong Industrial Complex by then.
Seoul “is on military readiness posture,” South Korea’s Blue House spokeswoman Kim Haeng said in a briefing. She said national security chief Kim Jang-soo also based the assessment on North Korea’s hint to foreign diplomats in Pyongyang to send personnel out of the country.
Meanwhile, the United State is a sea-based radar platform like the one pictured close to the North Korean coast to monitor the situation.
