International Desk: North Korea has launched an intercontinental ballistic missile, according to multiple military reports, just weeks after the country tested a similar projectile capable of hitting parts of the US.
The US defence department said Friday's launch appeared to be that of a long-range ICBM.
After South Korea's military and Shinzo Abe, Japan's prime minister, confirmed the report, the governments in Seoul and Tokyo convened meetings of their national security councils.
US President Donald Trump said the missile launch was "only the latest reckless and dangerous action by the North Korean regime".
He said the US "will take all necessary steps to ensure the security of the American homeland and protect our allies in the region".
Captain Jeff Davis, a Pentagon spokesperson, said the launch took place at about 14:45 GMT from Mupyong-ni, an arms plant in northern North Korea.
South Korea's Yonhap news agency, citing the country's military joint chiefs of staff, said the missile was launched from Jagang province, and landed in the East Sea.
The launch left analysts concluding that a wide swath of the United States is now in range of North Korean weapons.
David Wright, a physicist and co-director of the global security programme at the Union of Concerned Scientists, told the Associated Press news agency that if reports of the missile's maximum altitude and flight time are correct, it would have a theoretical range of at least 10,400 kilometres.
That means it could have reached Los Angeles, Denver or Chicago, depending on variables such as the size and weight of the warhead that would be carried atop such a missile in an actual attack.
In response to the North Korean launch, the US and South Korea conducted a live-fire exercise, Pentagon said in a statement.
It said the exercise used missiles that were fired into the "territorial waters of South Korea along the East Coast".
