May 15 (UPI) -- North Korea claimed the ballistic missile that was tested over the weekend reached a peak altitude of more than 1,300 miles before landing in an area 489 miles away.
Pyongyang's state-controlled Workers' Party newspaper Rodong Sinmun published photographs of the launch, which, according to state media took place at 5:28 a.m. Sunday, local time.
The newspaper showed the missile, identified as the Hwasong-12, and images of leader Kim Jong Un at the launch.
Kim said his country has secured an intercontinental ballistic missile capable of reaching the United States.
"The supreme leader Kim Jong Un called for the swift development of a mid- to long-range ballistic missile capable of not only mounting a standardized nuclear warhead, but also a large-size nuclear warhead," KCNA stated.
North Korea claimed the Hwasong-12 is capable of being equipped with bigger and more destructive nuclear bombs.
The Hwasong-12 is a midrange ballistic missile that can be equipped with a nuclear warhead, South Korean newspaper JoongAng Ilbo reported Monday.
The rocket was on display during a military parade on April 15 that commemorated the birth anniversary of founder Kim Il Sung.
The projectile is identical to a missile seen at the parade on a transporter erector launcher with its wheels covered, according to the JoongAng.
But North Korea's claim that it has secured the technology for the missile's atmospheric re-entry – the last stage of ICBM development – is being met with skepticism.
A source in South Korea's military told News 1 the "possibility is low" Pyongyang has mastered the technology.
Seoul's military authorities also said the missile is based on a new type of liquid-fuel engine that would make it capable of flying for a longer period of time.
