朝鲜火箭部队奉命做好袭击美国的准备

North Korean state media say leader Kim Jong Un has ordered preparations for rocket strikes on the U.S. mainland and military bases, after two U.S. stealth bombers flew training runs over South Korea.

The official Korean Central News Agency said Mr. Kim put his rocket units on standby Friday, after an overnight emergency meeting with top army commanders.  The order came hours after nuclear-capable U.S. B-2 bombers were deployed in ongoing joint military drills with South Korea.

The strategic bombers flew 20,000 kilometers non-stop Thursday from an air force base in the central U.S. to an island off the southwestern coast of the Korean peninsula, before returning to their home base. 

The mission was held amid increasing threats by North Korea against South Korea and the United States.  Pyongyang has severed all communication links with South Korea, the United Nations and the Red Cross.

朝鲜官方的朝中社说，金正恩与高层军队指挥官们连夜举行紧急会议后，星期五命令朝鲜火箭部队进入待命状态。在此几小时前，能够携带核弹头的美国B-2轰炸机进入部署，参加正在进行的美韩联合军事演习。

星期四，B-2战略轰炸机从美国中部一个空军基地不停顿地飞行2万公里，飞抵朝鲜半岛西南沿海的一个岛屿上空，然后返回基地。

在B-2轰炸机执行这一任务之际，朝鲜针对韩国和美国的威胁不断升级。平壤切断了与韩国、联合国以及红十字会的所有联络渠道。
