North and South Korean officials have struck a deal after negotiations to end tensions on the peninsula.
The dispute, over South Korea's anti-North propaganda broadcasts, had brought the two sides to the brink of armed conflict.
North Korea has moved its front line troops into "wartime state" after a recent exchange of shellfire with neighbouring South Korea, according to state media in the country.
This potential escalation in regional tensions comes after North Korea opened fire at a series of propaganda loudspeakers operated by its neighbour that were broadcasting propaganda messages across the border.
South Korea retaliated by firing artillery rounds towards North Korea, reportedly provoking Pyongyang to raise military readiness.
Seoul has promised to "powerfully counter-attack any North Korean provocations", the Yonhap news agency report.
