South Korea Military reported that North Korea fired two ballistic missiles over the sea off its east coast, said South Korea’s military, after the North vowed to take countermeasures against a joint military exercise held by South Korea, the United States and Japan.  

One short-range ballistic missile was launched from the Jangyon area in South Hwanghae Province at about 5:05 a.m. in a northeastern direction, said the South’s Joint Chiefs of Staff, or JCS.

Another unidentified ballistic missile was launched at around 5:15 a.m, it added, without providing further details.  

South Korea, the U.S. and Japan wrapped up their first, three-day trilateral multi-domain military exercise, codenamed “Freedom Edge,” aimed at strengthening their deterrence against North Korean threats.

The three countries have staged combined maritime and aerial exercises before, but Freedom Edge was the first trilateral exercise held across multiple domains, including air, maritime, underwater and cyber.
