North Korea has once again launched hundreds of trash-carrying balloons into South Korea, marking the third such campaign since May 28. In retaliation to South Korean civilian leafletting activities, North Korea has sent over 1,000 balloons carrying garbage and manure across the border. South Korea has responded by suspending a 2018 agreement with North Korea, allowing the South to resume military exercises and loudspeaker broadcasts near the border. The balloon launches have heightened tensions between the war-divided rivals, who are already facing a diplomatic impasse over North Korea’s nuclear ambitions.
