The North Korean military said on Tuesday that the US mainland was within the strike range of its strategic missile forces, Xinhua reported citing North Korea’s official KCNA news agency as saying.
“Strategic forces of the Democratic People’s Republic of Korea [DPRK] have placed the US forces on the Korean Peninsula, Japan, Guam and even the U.S. mainland within its target range,” KCNA quoted a spokesperson from DPRK’s National Defense Commission.
The announcement comes in a wake of a report that South Korea has reached a new missile deal with the United States , allowing Seoul to develop longer-range ballistic missiles capable of striking all of North Korea with stronger warheads.
In October 2006, North Korea became the world’s eighth nuclear power, conducting an underground nuclear weapons test.
