On Thursday night, a group of North Korean defectors sent 20 balloons containing about 300,000 leaflets, US dollars and USB sticks featuring a hit K-drama and songs across the border to the border city of Paju - a similar leaflet campaign between the two Koreas. Yonhap news agency reports.

North Korean defector Park Sang-hak, who is leading an anti-Pyongyang leaflet campaign, has vowed to continue sending propaganda leaflets to North Korea until North Korean leader Kim Jong-un is released by the North. Balloons carrying garbage to the South Don't apologize for sending. ,

"It is natural that there will be some trouble because he again did what he was requested not to do," Kim Yo-jong said in a statement carried by the North's official Korean Central News Agency. Launch more trash-carrying balloons in South Korea.

North Korea sent more than 1,000 garbage-carrying balloons to the South in recent weeks in retaliation for leaflet campaigns by South Korean activists.

In retaliation, South Korea resumed loudspeaker broadcasts on June 9 for the first time in six years. But to prevent the situation from getting out of control, he did not switch on the loudspeaker the next day.

For years, North Korean defectors and conservative activists in the South have sent anti-Pyongyang leaflets to the North via balloons to help encourage North Koreans to eventually rise up against the Kim family regime.

North Korea has stepped up its propaganda campaign amid concerns that an influx of outside information could pose a threat to the North Korean leader.
