North Korea launched what appears to be a ballistic missile Sunday afternoon, South Korea's military said.

"North Korea fired an unidentified projectile from a site this afternoon from the vicinity of Pukchang in Pyeongannam-do (South Pyeongan Province)," the Joint Chiefs of Staff said in a statement.

The JCS said North Korea's missile flew about 500 kilometers. President Moon Jae-in convened a National Security Council meeting to discuss North Korea's missile launch, officials said. (From news reports)
