NORTH Korea will automatically launch a nuclear attack if Kim Jong-un is ever assassinated, Pyongyang’s tyrannical constitution now states.

The terrifying last resort policy has been introduced in the wake of Ayatollah Ali Khamenei’s assassination by US-Israeli strikes in Iran.

The chilling revision states that retaliatory attacks will be launched in the event that the Supreme Leader is killed or incapacitated.

It was made on March 22 but made public on Thursday.

Article 3 of the nuclear policy now says: “If the command-and-control system over the state’s nuclear forces is placed in danger by hostile forces’ attacks … a nuclear strike shall be launched automatically and immediately.”

Any attempted assassination on Kim and his inner circle would be much more difficult than the US-Israeli operation in Iran in February.

North Korea’s borders are sealed tight – with the few people allowed to enter the country always closely monitored, making intelligence gathering extremely tough.

It comes as Pyongyang also plans to deploy a new type of artillery along its southern border, state media said on Friday.

The move could put Seoul within striking range – as Kim’s regime continues to deepen its hostility towards .

Kim was seen on Friday inspecting production of the new weapon – which is said to have a range of over 60km.

State media said the dictator was reviewing “a new-type 155-millimetre self-propelled gun-howitzer”.

Kim reportedly said: “[It will] provide significant changes and advantages to our military’s ground operations.”

Despite bids at making peace by South Korean officials, the North has repeatedly labelled Seoul as its main adversary.

Reports say the hermit kingdom is ramping up its punishments of ordinary citizens consuming foreign media – particularly and K-dramas.

It also recently wiped longstanding references to Korean unification from its constitution.

It comes after Kim binned the 70-year-old goal of peaceful reunification with South Korea.

He rebranded the North as a completely separate country for the first time since the 1940s.

The move was exposed by experts at a press conference in Seoul on Wednesday after secret documents were leaked by an academic, according to the Financial Times.

The new law explicitly defines Kim’s territory as bordering and to the north and the Republic of Korea to the south.

Experts say this is a massive shift, as Pyongyang has finally accepted that the peninsula is now two separate states at war.

For decades, the North maintained a constitutional mandate to achieve peaceful reunification with the South.

This national goal was established in the bitter aftermath of the 1945 division and the subsequent Korean War.

But the hermit nation has now gone silent on the changes, refusing to comment on the text revealed by South Korea‘s Unification Ministry.

While the new wording is not openly aggressive, analysts warn it’s a tactical move to treat the South like any other foreign enemy.

It also comes after to avoid being captured.
