North Korea threatened Saturday to carry out "indiscriminate strikes" on South Korea unless Seoul halts anti-Pyongyang broadcasts along their border.

In an "open warning" issued by the North Korean military's front-line command, the country demanded South Korea remove all means of psychological warfare or face "all-out military action."

"If they turn down the demand of the DPRK, it would start an all-out military action of justice to blow up all means for 'anti-north psychological warfare in all areas along the front,"

the North's command said in a statement carried by the North's official Korean Central News Agency.

"All means used for 'anti-North psychological warfare,' whether they are fixed or mobile, will never escape the strike of the KPA.

They should not forget that the KPA military action means indiscriminate strikes which envisage even possible challenge and escalating counteraction," it said.

DPRK stands for the North's official name Democratic People's Republic of Korea while KPA is the acronym for the North's Korean People's Army.

South Korea resumed the broadcasts on Aug. 10 in response to a landmine explosion inside the demilitarized zone that left two South Korean soldiers severely injured. South Korea has accused the North of planting the mines in violation of the Armistice Agreement that effectively ended the 1950-53 Korean War.

North Korea has denied the accusations. (Yonhap)
