North Korea launched a ballistic missile it claims is capable of "striking the whole" U.S. mainland.
The Pentagon says the missile was launched from a city near North Korea's western coast and that it flew east, landing in the Sea of Japan after traveling about 620 miles.
North Korea says its "newly developed" missile was tipped with a "super-large" warhead. This was the Hermit Kingdom's first launch since September.
U.S. President Donald Trump spoke with South Korean President Moon Jae-in following the launch. According to the White House, the two highlighted the threat North Korea poses and condemned the North's nuclear and missile programs.
Both leaders previously vowed to increase pressure on North Korea and repeatedly urged world leaders to do the same.
The U.S. State Department denounced the launch and called for unity in denuclearizing the North. It also said diplomatic options remain viable — "for now."
The United Nations Security Council will hold an emergency meeting Wednesday. Leaders from South Korea and Japan will reportedly seek additional sanctions against the North.
