It is reported by RIA Novosti with reference to the North Korean Central Telegraph Agency.

“North Korea will make the toughest response to any US military attempt on the principle of “nuclear bomb for nuclear bomb and total confrontation for total confrontation,” the report said.

According to a representative of the North Korean Foreign Ministry, while the US authorities are pursuing a "hostile policy," Pyongyang is not interested in dialogue with Washington.

Earlier, NATO Secretary General Jens Stoltenberg said that North Korea is of concern to the alliance, as it behaves "provocatively and destabilizingly."

It was also reported that a South Korean soldier accidentally opened fire during an exercise on the border with North Korea.
