SEOUL, South Korea (AP) — South Korea said Sunday it was bolstering its anti-Pyongyang propaganda broadcasts across the tense border with rival North Korea, after the North launched more trash-carrying balloons toward South Korea. South Korea’s Joint Chiefs of Staff said the North Korean balloons were flying Sunday morning north of Seoul, the South Korean capital, after crossing the border. “The North Korean military’s tension-escalating acts can result in causing critical consequences for it,” the South Korean Joint Chiefs of Staff said in a statement. “The responsibility for this situation is entirely on North Korea’s government.”Details of the expansion of South Korea’s loudspeaker operations were not immediately available. North Korea has floated more than 2,000 balloons to drop waste paper, scraps of cloth, cigarette butts, waste batteries and even manure on South Korea, though they have so far caused no major damage in South Korea.
