North Korean leader Kim Jong-Un has hailed the recent test of a submarine launched ballistic missile (SLBM) as a miraculous leap forward.

The North's official KCNA news agency reported Tuesday that Kim hosted a gathering of the scientists and technicians who were behind the test that was announced earlier this month.

According to KCNA, Kim congratulated the participants for producing an "eye-opening miracle" and a "historical event" that had left North Korea with a powerful strategic weapon.

North Korea’s powerful National Defense Commission (NDC) announced last week it has succeeded in miniaturizing its nuclear weapons.

"It has been a long time since we began miniaturizing and diversifying our means of nuclear strike," the NDC, the country's highest military body chaired by the leader, said in a statement carried by the official Korean Central News Agency.
