SEOUL, South Korea -- South Korea says North Korea has launched a ballistic missile toward the North’s eastern waters.

South Korea’s Joint Chiefs of Staff says the launch was made on Wednesday morning but gave no further details.

The reported launch came a day after North Korea threatened “shocking” consequences to protest what it called a U.S. spy plane’s reconnaissance activity near its territory.

The United States and South Korea dismissed the North’s accusations and urged it to refrain from any acts or rhetoric that raises animosities.
