The Pentagon has confirmed that North Korea fired a missile over Japan early Tuesday morning local time. From ABC News:

“We assess North Korea conducted a missile launch within the last 90 minutes,” Col. Rob Manning, director of press operations at the Department of Defense, said Monday evening in a statement. “We can confirm that the missile launch by North Korea flew over Japan. We are in the process of assessing this launch.

“North American Aerospsace Defense Command, or NORAD, determined the missile launch from North Korea did not pose a threat to North America. We are working closely with Pacific Command, Strategic Command, and NORAD, and we’ll provide an update as soon as possible,” Manning added.

CBS News reported that broadcaster NHK stated that the “missile broke into three pieces and fell into the waters off Japan’s Hokkaido island in the Pacific Ocean.” As of now, no one has not confirmed any damage or injuries from the missile.

Japan issued an alert to the people:

The government also stopped the bullet train service in northern Japan. From CBS News:

Japan’s Chief Cabinet Secretary Yoshihide Suga said Tuesday the missile launch was a threat that Tokyo would respond to firmly, Reuters writes.

“This ballistic missile launch appeared to fly over our territory. It is an unprecedented, serious and grave threat to our nation,” the top government spokesman said.

Tuesday’s news comes on the heels of Kim Jong Un’s firing of several short-range missiles into its East Sea on Friday. Those failed and exploded upon launch.
