Seoul on Saturday urged the North to immediately halt its plan of releasing propaganda leaflets against South Korea.
The South's Ministry of Unification made the request while expressing deep disappointment with the release plan.
It added that such an action is clearly a violation of the inter-Korean agreementwhich will worsen relations and hamper peace efforts on the peninsula.
The ministry also confirmed that the South's government is currently exercising strong measures against some civil groupsthat release leaflets against the North.
Earlier the same day, the North's Korean Central News Agency revealed a photo of an anti-South leaflet, reporting the North's plan of releasing them soon.
