The country's test of an intermediate-range ballistic missile (IRBM) allegedly crash-landed in Tokchon city and caused damages to some buildings there.
The Diplomat says that when it compared older and newer images of the failed missile's apparent crash site - which was said by its US source to be an industrial area in the city of Tokchon, 39 kilometres to the east of the launch - differences were apparent in the newer images. The missile never flew higher than approximately 70 kilometers.
The missile's failure was widely reported at the time but it was not previously known that the Hwasong-12 crashed in a populated area.
Despite North Korean dictator Kim Jong-un's recent boast about his nuclear button, a newer report has revealed that there might be some grave errors hiding behind the country's attempt at keeping up appearances.
Fortunately, it looks like the damage was confined to an industrial facility and greenhouse, but there appears to be residential buildings within the same shot frames.
In the weeks after the failed April 28 launch one of three failures in that month - the Hwasong-12 enjoyed a successful launch on May 14.
The damage was caused by the explosion which occurred when the missile's liquid propellant and oxidiser mixed on impact.
"The ICBM Hwasong-15 type weaponry system is an intercontinental ballistic rocket tipped with super-large heavy warhead. which is capable of striking the whole mainland of the U.S", North Korea's Central News Agency, a mouthpiece of the communist party, said on November 29.
The regime claimed that the missile could reach the United States.
The Tokyo-based Diplomat news website has reported that a missile test conducted in early 2017 went wrong and landed in a city instead.
Kim Jong-un could be seen walking alongside a huge new mobile launch platform, which Pyongyang said was specifically constructed for the missile, before the rocket was maneuvered into place.
The unpredictability and mobility of North Korea's launches mean the USA or its allies would have a hard time preempting such a launch or even knowing where to look for one.
But the fiery crash of a North Korean missile into a populated town demonstrates yet another threat posed by Pyongyang's nuclear ambitions.
