|The KN-11 missile was launched from waters near Sinpo and flew about 500km (300 miles) before falling into the Sea of Japan, a US official said. Japan's PM said it fell inside Japan's Air Defence Identification Zone, calling it a "reckless act".|
Wednesday's launch appears to have been its most successful test yet of a submarine-launched ballistic missile (SLBM). SLBMs are of particular concern because of the mobility of submarines and the ease with which launch preparation can remain undetected.
|The launch coincided with a meeting of foreign ministers from Japan, China and South Korea in Tokyo. The three regional powers agreed to "urge North Korea to exercise self-restraint regarding its provocative action, and to observe the UN Security Council's resolutions" - a rare agreement between them.|
|North Korea has conducted four nuclear tests to date but despite its claims, it is not yet believed to have the ability to mount a nuclear device onto a warhead.|
Pyongyang has been angered recently by several high profile defections, including its deputy ambassador to the UK, Thae Yong-ho.
