South Korea says it has restarted anti-Pyongyang propaganda broadcasts across the border in response to North Korea’s resumption of trash-carrying balloon launches

South Korea on Friday once again broadcast propaganda through speakers over its border—including playing K-pop and news on Samsung— in response to North Korea flying trash-filled balloons across the border for the eighth time since May, as tensions simmer between the neighboring countries.

South Korean broadcasts have previously draw sharp retaliation from North Korea. In 2015, South Korea recommenced loudspeaker broadcasts for the first time in 11 years, and North Korea responded by firing artillery rounds across the border, which South Korea responded to, according to authorities. There were no reported casualties.
