朝鲜举行炮兵实弹射击训练

North Korean state media says leader Kim Jong Un has overseen a live artillery drill near a sensitive sea border area, as Pyongyang continues to stir up tension on the Korean peninsula.

The Korean Central News Agency says Mr. Kim watched as the artillery uni

ts pounded what it called the "imaginary targets of the enemy" on two islands in the Yellow Sea. The Thursday report did not specify when the drill took place.

North Korea has threatened a nuclear war against the United States and made a series of threats against the South after the United Nations last week imposed sanctions for its latest nuclear test.

It is not believed to have the capacity to attack the U.S. with a nuclear weapon. But there is fear it may attack areas near the disputed border, which has been the site of several deadly clashes in recent years.
