North, South Korea Exchange Fire

North Korea has threatened military action against South Korea if the latter continues its “propaganda warfare,” the South Korean news agency Yonhap reports. North Korea has previously called broadcasted messages near the border “a direct action of declaring a war.” The two countries exchanged fire Thursday after North Korea fired at a speaker, with South Korea firing dozens of shells into its neighbor. Residents of South Korean border villages have been asked to relocate to shelters, in case the tense situation escalates.
