South Korea boosts propaganda loudspeaker broadcasts at border after North Korea flies more balloons

South Korea says it is bolstering anti-Pyongyang propaganda broadcasts across the tense border with rival North Korea, after the North launched more balloons likely carrying trash toward South Korea. The Cold War-style psychological battle between the two Koreas is adding to already-high tensions on the Korean Peninsula, with the rivals threatening stronger steps against each other. South Korea’s military says the North Korean balloons were flying Sunday morning north of Seoul after crossing the border. It later said that the South Korean military was expanding loudspeaker broadcasts along the Koreas’ 154-mile-long border.
