North Korea reportedly fired what is believed to be a "space launch vehicle" early Wednesday, prompting a string of sirens and emergency alerts to sound off in neighboring South Korea and Japan.
Citing South Korea's Joint Chiefs of Staff, South Korean media reported the projectile traveled over the Yellow Sea but did not affect Seoul city, despite earlier warnings being triggered for the metropolitan area.
An early analysis of the launch indicates the projectile disappeared from radar tracking before it reached its "expected drop point," South Korea media reported, adding that the launch was conducted out of the Tongchang-ri area.
Emergency warnings calling for individuals to seek shelter had been earlier issued for residents in Japan's Okinawa region and Seoul; however, it was later reported by US media that the warning issued for Seoul had been done in "error."
Since-surfaced video footage captured sirens sounding off in both countries.
Preliminary reports suggested the launch was that of a ballistic missile before it was determined it was likely that of the "space launch vehicle" Pyongyang had earlier hinted at in response to ongoing regional threats from the US and its allies.
An unidentified source has relayed to media that officials are presently investigating the possibility that the space vehicle may have either crashed or exploded midair.
An emergency national security meeting has since been called by the South Korean government.
