North Korea has carried out five nuclear tests and dozens of missile tests as it seeks to develop a nuclear-tipped intercontinental ballistic missile capable of hitting the US.
The North, now under a raft of UN crippling sanctions over its military programs, says it will continue those programs until the United States ends its hostility toward the country, slamming the controversial deployment of US Terminal High Altitude Area Defense (THAAD) in South Korea.

The Hyunmoo 2 is a critical component of the "kill chain" (a system created to detect a North Korean nuclear weapon or missile attack in advance and carry out a preliminary strike on the launch site), and with a range of 800km the missile could hit any point in North Korean territory.
