North Korea has fired “several” "strategic" cruise missiles, possibly nuclear-type, into the sea off the country's west coast, the fourth time in just over a week Pyongyang has launched such missiles.

North Korea has carried out a trial of its underwater nuclear weaponry system in a demonstration against the joint military exercises conducted this week by South Korea, the US, and Japan, which “seriously” threatened the “security” of Pyongyang.

North Korea’s leader, Kim Jong-un, calls for constitutional change to identify the south as “number one hostile state.”

The North Korean leader has inspected new photos of the ‘target regions’ taken by Pyongyang’s spy satellite.

Over the past year and a half the DPRK has launched an unprecedented number of missiles, which the US has tried to deter by expanding preexisting sanctions against Pyongyang.

North Korean leader Kim Jong-un asserts ongoing nuclear development is in response to the "worst threat" posed by the US and its regional allies, South Korea and Japan.

North Korea has amended its constitution to bolster its nuclear power status, citing “provocations” from the US.
