North Korea floated balloons carrying trash towards South Korea on Sunday, South Korea's military said, declaring it would respond with "full-scale" loudspeaker broadcasts.
The South Korean military said the North's actions raising tensions near the heavily armed border could have fatal consequences, adding the North Korean regime would be solely responsible.
"As we warned several times, the military will carry out loudspeaker broadcasts in full scale and on all fronts starting 01:00 p.m. today," South Korea's Joint Chiefs of Staff said, calling the North's launch of balloons vulgar and shameful.
