An intermediate-range ballistic missile (IRBM), named the Hwasong KN-17, was sacked from Pukchang Airfield in South Pyongan Province, 40 miles north of Pyongyang on April 28 past year, the source told The Diplomat.
North Korea is reportedly in the early stages of testing another intercontinental ballistic missile, only a month before the South will welcome countries from across the world for the Winter Olympics.
The Diplomat reports satellite imagery shows the missile struck a complex of industrial or agricultural facilities, located near residential and commercial buildings in Tokchon.
However The Diplomat said it was impossible to ascertain whether there was any loss of life.
Initially, reports had suggested that the intermediate-range ballistic missile (IRBM) had exploded into pieces in mid-flight but new evidence suggest that it in fact crashed into the city of 200,000.More news: Christians mark Christmas with due religious fervour
The damage was caused by the explosion which occurred when the missile's liquid propellant and oxidiser mixed on impact.
While both landed in the ocean, this new report of a failed missile test certainly poses the possibility that a failed missile test over Japan could cause grave destruction there. But the true damage done to buildings is a guess at best given available satellite data.
Dr Baker, an adviser to Reagan during the Cold War, claimed North Korea is taking "considerable" risks, which could see a missile veering off course and hitting the wrong target. It is believed that the success of the missile paved way for Hwasong-14/KN20 intercontinental-range ballistic missile (ICBM), unveiled by North Korea previous year.
In November a successful Intercontinental Ballistic Missile launch, the massive Hwasong-15 that led Prime Minister Malcolm Turnbull to label North Korea "a criminal nation", proved Kim Jong-un could reach "all parts of the U.S. mainland", the communist state claimed. The successful launch has been followed by a couple of more successful launches which has left the United States of America fuming.
