North Korea has sent rubbish-carrying balloons towards the South, the South Korean military has said.
Anti-Pyongyang activists in the South said they have sent balloons with leaflets against leader Kim Jong-un.
"North Korea is again floating (suspected) balloons carrying trash towards the South," the Chiefs of Staff said in a statement, advising the public to refrain from touching the balloons if spotted and to report them to authorities.
Pyongyang announced a halt to the balloons tomorrow but days later, a South Korean group called 'Fighters for Free North Korea' said it had sent 10 balloons with USB thumb drives containing K-pop music and 200,000 leaflets against leader Kim Jong-un.
The South Korean military is "closely monitoring with vigilance" because of "the possibility of more rubbish balloons descending tomorrow", its spokesperson said.
North Korea had said it would respond with "wastepaper and rubbish" a hundred times the amount if more South Korean leaflets were sent.
Another group, comprising North Korean defectors, said it had sent 10 balloons on Friday with 200,000 anti-Pyongyang leaflets, 100 radios, and USB thumb drives containing a speech by South Korean President Yoon Suk Yeol.
Jang Se-yul, the leader of the group, said his organisation will not stop its campaign, "whether Kim Jong-un sends trash-carrying balloons again or not".
Last week, the North Korean balloons landed in a number of locations in the South, and were found to be carrying rubbish such as cigarette butts, cardboard scrap and waste batteries.
In response to the balloons, on Tuesday South Korea suspended a 2018 military deal with the North which was meant to reduce tensions between the neighbours.
Authorities in Seoul have condemned the North Korean balloons as a "low-class" act and threatened counter-measures that it said Pyongyang would find "unendurable".
