(CNN)North Korea fired a projectile into the Sea of Japan, also known as the East Sea, on Wednesday morning, US and South Korean officials said.
The United States believes the projectile was likely a ballistic missile, according to a US official. It is one of several the country has test-fired in recent months.
The projectile was launched at 6:42 a.m. Seoul time, from a site in the vicinity of Sinpo, South Hamgyong Province, a South Korean Defense Ministry official said. It flew a distance of around 60 kilometers, South Korean officials said.
The North Koreans use Sinpo shipyard for their submarine activity, and US satellites have observed increased activity there in recent days, a second US official said.
US Pacific Command said it detected and tracked a North Korean missile launch at 11:42 a.m. Hawaii time April 4, according to a statement. Pacific Command’s initial assessment is that the missile was a KN-15 medium range ballistic missile.
“The North American Aerospace Defense Command determined the missile launch from North Korea did not pose a threat to North America,” said Cmdr. Dave Benham, spokesman for US Pacific Command.
