South Korea says it will restart loudspeaker propaganda broadcasts into the North, after Pyongyang sent hundreds more rubbish-filled balloons across the border.

“We will install loudspeakers against North Korea today and carry out the broadcast,” the president’s office said in a statement on Sunday.

North Korea sent more than 300 rubbish-filled balloons across the border on Saturday, Seoul’s military said, with the president’s office saying this had forced it to take “corresponding measures”.

It said that “the responsibility for the escalation of tension between the two Koreas will be entirely up to the North”.

“Although the measures we are taking may be difficult for the North Korean regime to endure, they will deliver messages of light and hope to the North Korean military and citizens,” the president’s office added.

South Korea’s joint chiefs of staff said it detected the North launching about 330 balloons toward the South since Saturday night and about 80 were found in South Korean territory as of Sunday morning.
