Pyongyang, October 20 (QNA) - The sister of North Korean leader Kim Yo-jong said Monday the situation at the southern border is "very unstable," noting that the country is reviewing a possible resumption of loudspeaker broadcasts along the border.

The remarks came after Pyongyang has repeatedly denied responsibility for a land mine explosion last month that injured three South Korean soldiers, two of them seriously, and dismissed Seoul's findings that land mines were deliberately planted by North Korea.

"Now the situation of the southern border is very unstable," Kim said in a statement carried by the Korean Central News Agency (KCNA). She accused the South Korean military of threatening North Korean soldiers and heightening tension and said such actions have "gone beyond the red line," following what she called "a fabricated 'mine explosion farce.'"

She claimed the South conducted 2,870 rounds of loudspeaker broadcasts and fired 201 warning shots between August 1-October 17.

Kim said the North Korean military is considering deploying more tactical strike means along the border and resuming loudspeaker broadcasts to address the situation.

North Korea had halted its cross-border broadcasts in response to Seoul’s decision last year to stop loudspeaker broadcasts along the border, a measure taken as part of President Lee Jae Myung’s efforts to restore trust between the two Koreas. (QNA)
