North Korea on Thursday issued the customary denunciation of South Korean military exercises that marked the North's mortar attack on Baeknyeong Island a year ago.
The North Korean military in a statement carried by the official Korean Central News Agency threatened to engulf Cheong Wa Dae in a "sea of fire" if any shots fired reached North Korean territory.
The flames would "spread to eradicate the base of the traitors," it thundered.
It claimed the deadly shelling of Yeonpyeong Island had been "a just act of self-defense against those who instigated provocations in our sacred territorial sea despite our warning." Wednesday's exercises were "a new political and military provocation against our military and people," showing the South "has not learned the lesson of a year ago."
