North Korea’s army has threatened that it is ready to enter the demilitarized zone that divides North and South Korea.
Kim Yo-jong, the sister of North Korean leader Kim Jong-un, said on the Weekend that she had ordered the army to be ready for the step.
Army says it is ready to “turn the front line into a fortress and heighten military vigilance”.
Sources said that the warning has been given in response to defector groups in the South sending propaganda material north.
North and South Korea are divided by the demilitarised zone (DMZ), buffer along the border through which the countries are separated since the Korean War in the 1950s.
The North Korean forces said it was “studying an action plan” for the army to go “into the zones that had been demilitarized”.
The general staff said it was on “high alert” and ready to “rapidly and thoroughly” to work on the orders given by the government.
Kim Yo-jong, who enjoys a senior role in North’s politics, said, “I feel it is high time to surely break with the South Korean authorities,”
She pledged to take “action”. She also said, “Rubbish must be thrown into the dustbin.”
