Seoul resumes loudspeaker propaganda against North

South Korea on Sunday resumed a loudspeaker propaganda campaign against the North after Pyongyang sent a fresh barrage of trash-filled balloons across the border. 

The president's office had earlier confirmed the move, describing it as "corresponding measures" for the more than 300 trash-filled balloons Pyongyang sent across the border.

The Seoul city government, as well as officials in surrounding Gyeonggi province, sent out a text alert to residents on Saturday warning about the new balloons.
