North Korea has launched around 190 balloons filled with scrap paper and other waste toward the South in its resumed balloon campaign, with many found in Seoul and surrounding areas, military officials said Saturday, Paralel.Az reports citing Yonhap News Agency.

North Korea floated the balloons from Friday night to early Saturday morning, and around 100 have landed in the capital and its surrounding Gyeonggi Province so far, the Joint Chiefs of Staff said.

No hazardous materials have been found in the balloons, which contained only scrap paper, plastic pieces and bottles.

North Korea resumed its latest balloon campaign Wednesday, continuing for the fourth consecutive day Saturday.

Since late May, the North has launched thousands of balloons carrying trash in retaliation against anti-Pyongyang leaflets sent across the border by North Korean defectors and activists in South Korea.
