Pyongyang said on July 4 that it had successfully launched its first intercontinental ballistic missile (ICBM), a claim that Washington has corroborated and Moscow has disputed.
North Korea said the missile traveled 580 miles and reached an altitude of 1,740 miles during its 39-minute flight before "accurately hitting the target waters in the open sea" in the Sea of Japan.
US officials have also said the test marked North Korea's first successful firing of an ICBM.
But the Russian Defense Ministry has said its warning system showed that the Hwasong-14 only reached a maximum altitude of 332 miles and flew just 316 miles. That flight distance and altitude correspond to the characteristics of a medium-range ballistic missile, not an ICBM, the ministry said.
