North Korea says it has successfully tested a new type" of submarine-launched ballistic missile, as the nuclear-armed country pursues ever more improved weapons.

The device had lots of advanced control guidance technologies", the official Korean Central News Agency said on Wednesday, adding that it was launched from the same vessel that the North used in its first submarine-launched ballistic missile (SLBM) tests five years ago. The latter point casts doubt on claims by Pyongyang in 2015 that it had launched a submarine-based missile.
