North Korea fired an unidentified projectile into the waters off the Korean Peninsula on Tuesday, according to South Korea's Joint Chiefs of Staff.
The Joint Chiefs of Staff did not provide any further details about the launch, The Korea Herald reported. This launch is Pyongyang's first weapons test of this year and comes roughly 80 days after North Korea test-fired submarine-launched ballistic missiles into the Sea of Japan, known in South Korea as the East Sea, in October.
"Our military is maintaining readiness posture in preparation for a possible additional launch while closely monitoring the situation in close cooperation with the United States," South Korea's Joint Chiefs of Staff said.
Japan's coast guard, which was the first to report North Korea's launch, said the missile may have been ballistic but did not elaborate, Reuters reported.
