Emergency alert sounds in Japan after North Korea launches multiple missiles

An emergency alert for people in parts of central and northern Japan to seek shelter was triggered on Thursday following North Korea's latest multiple missile launches, including a possible failed intercontinental ballistic missile.

"At the moment, there are no reports that they (the missiles) fell inside Japan's Exclusive Economic Zone (EEZ)," Japanese Chief Cabinet Secretary Hirokazu Matsuno told a news conference.

North Korea's multiple launches on Thursday came a day after the country fired at least 23 missiles, the most in a single day, including one that landed off South Korea's coast for the first time.
