North Korea displayed its submarine-launched ballistic missiles (SLBM) for the first time on Saturday ahead of a massive military parade in the capital, Pyongyang.

North Korea warned the United States on Saturday to end its "military hysteria" or face retaliation as a U.S. aircraft carrier group steamed towards the region and the reclusive state marked the 105th birth anniversary of its founding father.

State TV showed images of the Pukkuksong-2 SLBMs on trucks waiting to be paraded in front of leader Kim Jong Un.
