North Korea has shut off all lines of communication with “enemy” South Korea. This includes shuttering several military-to-military hotlines, plus another phone line meant to directly connect North Korean leader Kim Jong Un and South Korean President Moon Jae-in at a moment’s notice. Officials in Pyongyang say they’re giving Seoul the cold shoulder because North Korean defectors in South Korea flew balloons over the border carrying leaflets and SD cards, likely with information about the outside world. It’s illegal for average North Koreans to consume information that is not approved by the state. Experts say North Korea may be using the incident to manufacture a crisis between the two nations.
