This is reported by CNN. One Pentagon official said that on July 21, on Friday, vehicles were seen in the city of Kusong in North Korea that were carrying numerous ballistic missile launch equipment.
It is assumed that North Korea may timed launch of the missile for the holiday in honor of the end of the Korean War, which is celebrated annually on July 27. Earlier in the DPRK they said they could strike at any point in the world. However, the deputy chairman of the Joint Chiefs of Staff at the Pentagon, Paul Selva, noted that they were unable to make an accurate strike because of the undeveloped guidance and navigation system.
Recall, as reported URA-Inform, the US does not rule out an armed conflict with the DPRK.
