"Our military is thoroughly monitoring the North's activities in the border area amid close cooperation with the United Nations Command," the official said.

The border violations came as North Korea has been deploying large numbers of troops in front-line areas since April to conduct an array of activities, such as planting mines, erecting walls and building roads for military operations.
