North Korea releases video of July 4 missile launch

An assessment of North Korea's launch is ongoing, according to officials.

— -- A North Korean state broadcaster has aired video of this week's missile launch, showing the moment the intercontinental ballistic missile took off, leaving plumes of smoke fanning out along the earth.

"The United States strongly condemns North Korea's launch of an intercontinental ballistic missile," Tillerson said in a statement. "Testing an ICBM represents a new escalation of the threat to the United States, our allies and partners, the region, and the world."

The missile, which ultimately fell into the sea between in the Sea of Japan the Korean Peninsula and Japan, was launched into a high-altitude trajectory of 1,730 miles and flew horizontally about 575 miles, according to the U.S. and South Korea.

The missile was launched from an airfield in Kusong, a city in North Korea's far northwestern corner, an area used for launches in the past.

A spokesman for Japan's Cabinet said the missile landed inside Japan's exclusive economic zone, which extends 200 miles from its shores.

In response to the launch, the U.S. Army and military personnel from South Korea conducted a missile exercise of their own, firing two short-range missiles into the Sea of Japan, the U.S. Army said in a statement, "countering North Korea’s destabilizing and unlawful actions."

A defense official said the U.S.-South Korean "show of force" involved two missiles: one ATACMS fired from the U.S. and one Hyunmoo II fired by the South Korean military.
