The missile, believed to be an ICBM by the Pentagon, was launched from Sain Ni in North Korea and flew roughly 620 miles before landing in the Sea of Japan.
South Korea's Yonhap News Agency, which first reported the launch, said the missile launch happened around 3 a.m. in North Korea. South Korea’s military had reportedly staged a “precision strike” missile exercise in response.
An official told Fox News the U.S. military was still analyzing the data to determine what type of ballistic missile was launched. North Korea has been working hard to perfect “re-entry” technology to one day have a warhead be able to survive re-entry into Earth’s atmosphere.
