North Korea fired off an unidentified projectile Wednesday, but the launch appears to have failed soon after liftoff, South Korea's military said.

The Joint Chiefs of Staff (JCS) said the North launched the projectile from the Sunan area in Pyongyang at 9:30 a.m. Other details were not immediately available.

"The intelligence authorities of South Korea and the U.S. are conducting an additional analysis," the JCS said in a text message sent to reporters.
