Japan puts its military on alert to shoot down any North Korean rocket that threatens it following an announcement by North Korea of a planned "Earth observation launch".
North Korea test-launches what is presumed to be its first intercontinental ballistic missile 933 kilometers into the Sea of Japan within Japan's Exclusive Economic Zone. An American expert theorizes the ICBM, which reached an altitude of 2,802 km, could potentially reach the U.S. state of Alaska.
North Korea launches a Short-Range Ballistic missile near Wŏnsan towards the Sea of Japan, according to South Korea. The missile reportedly lands in Japan's exclusive economic zone (EEZ) after traveling 450 km.
Amid growing concern about North Korea's ballistic missile capability, South Korea, Japan and the U.S. are to hold their first ever joint anti-missile exercise next month, according to South Korea's Ministry of National Defense. The three countries will practice "detecting and tracing a hypothetical North Korean missile," said a ministry official.
South Korea has determined North Korea is capable of mounting a nuclear warhead on its medium-range Rodong-1 ballistic missile, which could reach all of South Korea and most of Japan, according to a senior government official.
Japan deploys two MIM-104 Patriot surface-to-air missile interceptor systems in Tokyo in preparation for any North Korean ballistic missiles potentially heading for the city. The deployment comes amid concerns of an imminent North Korean missile launch following the detection of "increased activity" at a North Korean missile facility.
