North Korea launched an unidentified shell into the Sea of Japan, Yonhap News Agency reported Tuesday, Sept. 28, citing the South Korean Joint Chiefs of Staff.
Authorities in Seoul are currently analyzing data on the origin of the projectile, as well as launch and flight characteristics, the agency noted.
Kyodo wrote that the Japanese government suspects it was a ballistic missile.
Earlier, on September 15, North Korea conducted two missile launches toward the Sea of Japan. Both are believed to be ballistic missiles. The interval between the launches was about five minutes.
Japanese Defense Minister Nobuo Kishi said that the rockets fell in the Sea of Japan within Japan’s exclusive economic zone. He said a re-analysis determined that the missiles flew a distance of about 750 kilometers and had a maximum flight altitude of about 50 kilometers.
Pyongyang explained that the missile launches were a test of a railroad missile system. As part of the test, the missiles flew 800 kilometers before reaching their target in the Sea of Japan.
South Korea successfully tested a submarine-launched ballistic missile on the same day.
After the test, the Kremlin called on North Korea and the Republic of Korea to avoid escalating the situation. As Russian presidential spokesman Dmitry Peskov noted, the Russian military is closely monitoring developments in the region.
