North Korea launched a ballistic missile from its western region into the sea off its east coast on Tuesday, South Korea's military said, ahead of a summit of leaders from the Group of 20 countries in Germany later this week.
The missile flew for about 40 minutes and may have landed in Japan's Exclusive Economic Zone (EEZ), the Japanese government said, adding that it had strongly protested what was a clear violation of UN resolutions.
The missile was launched around 0040 GMT (8.40 p.m. ET) from an airfield in Panghyon, about 100 km (60 miles) northwest of the North's capital, Pyongyang, the South Korean military said.
