N. Korea fired an unspecified missile from submarine in waters off Sinpo Sunday: S. Korean military

SEOUL, March 13 (Yonhap) -- North Korea fired an unspecified missile from a submarine over the weekend, Seoul's military said Monday, in apparent protest over a regular South Korea-U.S. combined military exercise to begin this week.

The Joint Chiefs of Staff (JCS) said that it detected the missile launched from the North's eastern coastal city of Sinpo on Sunday morning. It did not immediately provide other details.

"While strengthening its monitoring and vigilance, our military is maintaining a full readiness posture in close cooperation with the United States," the JCS said in a text message sent to reporters.

The latest launch came on the eve of the allies' major Freedom Shield exercise, which kicks off on Monday. The North has decried the exercise as "preparations for a war of aggression" against it.
