North Korea Fires 2 Ballistic Missiles At South Korea

North Korea on Monday launched two ballistic missiles, South Korea's military confirmed -- the latest in a series of weapons tests by Pyongyang that have soured relations with Seoul.

A short-range ballistic missile was launched in the early morning hours, the South's military Joint Chiefs of Staff said in a statement. About 10 minutes later, a second missile, this one as yet unidentified, was detected, it added.

"Our military has strengthened surveillance and vigilance in preparation for further launches," the JCS said, adding it had shared information about the incidents with the United States and Japan.
