South Korea restarted loudspeaker broadcasts directed at North Korea on Sunday after Pyongyang launched balloons carrying trash and manure over the border.

Around 330 balloons were launched by the North, about 80 of which dropped into South Korea, prompting the South to engage in psychological warfare.

The broadcasts include world news and K-pop music and aim to deliver a message of hope to North Korean troops and citizens while warning Pyongyang.

Tensions have risen since South Korean activists continued sending anti-Pyongyang leaflets, defying North Korea's warnings.

The sound of these broadcasts can travel over 20 kilometers into the North.
