North Korea fired several “unidentified” cruise missiles on the country’s east coast on Sunday, the ROK military reported, days after it tested a new nuclear-capable cruise missile.

The launch occurred around 8:00 a.m. KST at the sea near the North Korean port of Sinpho, according to the ROK Joint Chiefs of Staff (JCS).

South Korean and U.S. intelligence agencies are currently analyzing the incident, the JCS added.

“The ROK military is maintaining close contact with the U.S., while enhancing surveillance and vigilance, and is monitoring further signs and activities of North Korea,” according to the statement.
