North Korea has test-fired a missile from a submarine off its east coast, U.S. Pacific Command announced Tuesday.
"The launch of a presumed KN-11 submarine-launched ballistic missile occurred off the coast of Sinpo. The missile was tracked over and into the Sea of Japan, approximately 300 miles off the coast of North Korea," PACOM said, in a news release.
U.S. officials said the missile launch did not pose a threat to North America.
PACOM condemned the launch, saying it only serves to "increase the international community's resolve to counter the DPRK's prohibited activities, including through implementing existing U.N. Security Council sanctions."
The launch came two days after South Korean and U.S. troops began their annual summer drills that the North calls an invasion rehearsal.
North Korea usually responds to the regular South Korea-U.S. military drills with weapons tests and fiery warlike rhetoric.
