North Korea sent more balloons likely carrying trash to South Korea, Seoul's Joint Chiefs of Staff (JCS) said on Sunday.
The JCS warned that balloons may reach the capital city of Seoul and the surrounding Gyeonggi Province.
Since late May, Pyongyang has launched thousands of trash-filled balloons toward South Korea in response to spreading anti-Pyongyang leaflets by South Korean activists. Seoul decided no to shoot down the balloons due to security concerns.
