Two weeks ago, the U.S. deployed a nuclear-powered submarine capable of carrying about 150 Tomahawk missiles to South Korean waters for the first time in six years.

A video taken by a person on board shows passengers’ hair being whipped by air blowing into the cabin through the open door.

South Korea’s president on Tuesday called for stronger air defenses and stealth drones after North Korean drones crossed the border for the first time in five years.

North Korea fired an intercontinental ballistic missile that landed near Japanese waters Friday in its second major weapons test this month.

At least one missile landed near the rivals’ tense sea border. South Korea quickly responded by launching its own missiles.

The statement came hours before the U.S. and South Korean foreign and defense chiefs met in Seoul for their first joint talks in five years to discuss North Korea’s nuclear program

A day after threatening long-range rocket launches, North Korea declared Tuesday that it has upgraded and restarted all of its atomic fuel plants so it can produce more — and more sophisticated — nuclear weapons.
