South Korea's Joint Chiefs of Staff(JCS) said it believes that North Korea fired a Hwasong-14 class long-range ballistic missile early Wednesday morning.
 
The JCS said the missile was launched from the vicinity of Pyongsong, South Pyongan Province, at around 3:17 a.m.
 
The Air Force's E-737 surveillance system, dubbed Peace Eye, was the first to detect the missile within a minute of its launch, followed by Aegis destroyers and radars in the East Sea.
 
The projectile traveled toward the East Sea for about 960 kilometers at a peak altitude of about 4,500 kilometers.
 
The Pentagon confirmed the launch saying an initial assessment indicates that the missile was an intercontinental ballistic missile.
 
The JCS said allies are "maintaining the ability and posture to strike the origin of provocation and command and support facilities with precision anytime, on the ground, at sea and in the air."
 
The North Korean missile launch breaks a 75-day hiatus in its provocations.
