朝鲜威胁要让韩国一岛屿陷入火海

North Korean leader Kim Jong Un has threatened to attack a South Korean border island in response to Seoul and Washington's ongoing annual military exercises.

Mr. Kim was quoted in state media Tuesday as telling front-line troops to prepare to destroy "enemy targets" on Baengnyeong island, near the site of a deadly North Korean attack in 2010.

It is the latest in a series of dramatic threats by North Korea following last week's U.N. sanctions over its latest nuclear test.

Seoul's Defense Ministry spokesperson Kim Min-seok on Tuesday said there is no evidence of an impending attack or weapons test by North Korea, which he said is just trying to put "psychological pressure" on the South.
