South Korean National Security chief Kim Jang-soo said that Seoul "is on military readiness posture", Yonhap news agency reported Sunday. "As of now, nothing out of the ordinary has been detected," South Korea's Blue House spokeswoman Kim Haeng said in a briefing on Kim's behalf. "If limited war is to break out, North Korea should bare in mind that it will receive damages many times more," she said. South Korea's presidential office said Pyongyang may make additional provocations, including missile test-fires, before or after Wednesday, the deadline it has provided to foreign countries for requesting help in evacuating their embassies from the communist country.
