朝鲜表示，要终止跟美国仅存的联络方式，作为对美国因践踏人权而制裁朝鲜领导人金正恩的报复。
平壤星期一说，他们已知会美方，朝鲜正式中断通过驻联合国办公室跟美国的任何联系。
美国上星期对金正恩和另外一些朝鲜官员实施个人制裁。此前，朝鲜因其核武器项目已经受到了制裁。
星期一早些时候，朝鲜威胁要采取行动，因为美国和韩国此前宣布要在韩国部署先进的导弹防御系统。
朝鲜做出这一威胁的几天前，美国和韩国宣布，针对平壤进行的一系列弹道导弹试射和核试验，计划在朝鲜半岛部署反导弹“萨德”系统，部署的具体地点和时间尚未宣布。
North Korea says it is closing one of the last lines of communication with the United States in retaliation for Washington placing sanctions on leader Kim Jong Un for human rights abuses.
Pyongyang said Monday it has told the U.S. the North is effectively ending all diplomatic communications with Washington that have been conducted through the U.N. offices in New York.
Last week, the U.S. placed personal sanctions on Kim and several other North Korean officials, in addition to sanctions already in place on the country for Pyongyang's nuclear weapons program.
Earlier Monday, North Korea threatened to take "physical action" after the U.S. and Seoul announced plans for deployment of a sophisticated missile defense system in South Korea.
Pyongyang made the threat several days after Washington and Seoul revealed plans to use the Terminal High Altitude Area Defense system - THAAD - on the Korean peninsula following a series of ballistic missile and nuclear tests by Pyongyang. The location and timing of the deployment have not been announced.
