KIM Jong-un has stoked up World War Three fears with a double ballistic missile test as South Korea fires its first sub-launched rockets.
South Korean President Moon Jae-in attended a test firing of a submarine-launched ballistic missile (SLBM) just hours after rival Pyongyang launched two rockets in a chilling escalation of tensions along the Korean peninsula.
It comes as Jei-in was present at an underwater SLBM test aboard the new 3,000-tonne class Dosan Ahn Chang-ho KSS submarine last month, his office said.
This makes South Korea the only country to field such weapons without nuclear warheads.
The Blue House said in a statement: "President Moon evaluated that today’s successful test produced results that would make the people feel more relieved and proud, praising the hard work of researchers and related personnel
"The possession of an SLBM has a significant meaning for the purpose of securing deterrence capabilities responding to omnidirectional threats and will play a big role in the establishment of national self-defense and peace on the Korean Peninsula in the future."
Other countries that have tested or developed SLBMs, including the US, Russia, China, Britain, France, North Korea, and India, have typically designed them to carry nuclear weapons.
Experts say this could have ground-breaking implications for North Korea, the US, and could usher in a nuclear arms race in the Koreas, according to Reuters.
It comes as Pyongyang fired what appear to be a ballistic missile off its east coast just two days after it claimed it was testing new weapons on Wednesday.
The unknown projectile, believed to be a missile, flew towards the Korean Peninsula's east coast.
