In an article entitled "A reunification war will be a blitzkrieg" on Thursday, the North Korean propaganda website Uriminzokkiri said, "If a blitzkrieg should occur, it will be finished in just a few days."

North Korea on Thursday warned it would finish any war on the Korean Peninsula in three days and turn South Korea into a nuclear wasteland.

"Once given orders, North Korean artillery will rain 120,000 rounds at a time over the South, and its special troops can pulverize South Korean bases of the Air Force, the Navy, radars, and missiles in rear areas," it added.

It also threatened to tear down "concrete barriers" with a single miniaturized nuclear weapon and clear the way for troops to march south.

The whole of South Korea with its large population, industrial complexes and nuclear power plants will be reduced to rubble, it warned.

Meanwhile, the North reportedly staged an air defense drill in Pyongyang on Feb. 26-28 in response to the South Korea-U.S. exercises.

Evacuation and blackout drills were carried out, a source said Thursday. "Tanks and armored vehicles were mobilized at night, and the roaring vehicles made so much noise that Pyongyang citizens couldn't sleep."
