North Korea launched a suspected intermediate-range ballistic missile over Japan on Tuesday, authorities in Tokyo and Seoul said. Although the launch was likely just a test, officials in the Japanese regions of Hokkaido and Aomori urged residents to take cover early on Tuesday morning. "North Korea appears to have launched a missile," the Japanese government said in a rare activation of its J-Alert system. "Please evacuate into buildings or underground." South Korean President Yoon Suk-yeol condemned Pyongyang's "reckless provocations" while Japan's prime minister, Fumio Kishida, called the missile launch "barbaric." No damage or injuries were reported. Later on Tuesday, the South Korean Ministry of Unification said Pyongyang was unresponsive on the inter-Korea hotline used for negotiations between the two countries.
