North Korea threatens South with "sea of fire"

On Wednesday, South Korea mobilized aircraft, rocket launchers, artillery guns and naval boats for the first anniversary of the artillery attack on a military garrison and fishing community on Yeonpyeong Island in the Yellow Sea. Two marines and two construction workers were killed in the attack, the first on a civilian area since the 1950-53 Korean War.

A similar "sea of fire" threatens to engulf Seoul's presidential Blue House if South Korean forces fire a single shot into North Korean territory, the North's People's Army warned in a statement from Pyongyang.

Pyongyang accuses Seoul of provoking last year's attack, saying it struck after warning the South not to hold live-fire drills in the disputed waters. South Korea has said it fired shells southward, not toward the North, as part of routine exercises last year.

"If they dare to impair our dignity again, the deluge of fire on Yeonpyeong Island will lead to the sea of fire in Blue House" in Seoul, the North's People's Army warned in a statement from Pyongyang. "They should not forget the lesson taught" by the island shelling.
