On 28 July, North Korea conducted its 12th missile test since February 2017.
So why has this latest launch created such tensions between North Korea and the United States?
According to David Wright of the Union of Concerned Scientists, if the Hwasong-14 was fired under proper flight conditions, it could reach a target more than 6,700km away. This puts the missile firmly in the long-range or intercontinental ballistic missile (ICBM) bracket, and means it could potentially hit the US base on the island of Guam as well as Alaska.
NOTE: The video was released on 7th July (before the latest missile test on July 28)
