North Korea said Monday it successfully tested a mid-to-long range missile capable of carrying a "large scale heavy nuclear warhead."
The country's leader, Kim Jong Un, supervised the launch and later warned U.S. leaders not to misjudge the fact that the country is in North Korea's "sighting range for [a] strike," Reuters reports citing the country's KCNA news agency.
North Korea launched the missile near the city of Kusong and it landed in the Sea of Japan, just 60 miles from eastern Russia, according to CNN.
The missile reached an altitude of 1,312 miles and was in the air for approximately 30 minutes.
After the launch, North Korea issued a warning to the United States.
"If the U.S. awkwardly attempts to provoke the DPRK, it will not escape from the biggest disaster in the history," Kim said via KCNA.
North Korea is believed to be developing an intercontinental ballistic missile capable of reaching the U.S. mainland. ABC News reports that the U.S. officials believe the ballistic missile North Korea launched was actually a medium range KN-17 missile.
David Wright, co-director of the Union of Concerned Scientists, wrote in a recent blog post that if the missile did, in fact, reach the reported height, it could be capable of reaching Guam, a U.S. territory. As CNN points out, Guam is home to Andersen Air Force Base.
