North Korea has unveiled its latest intercontinental ballistic missile at a military parade in Pyongyang to mark the 80th anniversary of the founding of the ruling party.
Named the Hwasong-20, its size suggests that it could carry multiple nuclear warheads.
The isolated state has continued to expand its nuclear arsenal in recent years, causing concern in the West and closer to home.
Footage shown on North Korean state TV showed leader Kim Jong Un overseeing the parade.
