The threats come after the UN voted unanimously to restrict shipments of fuel to Pyongyang and for a total ban on textile exports.
In a statement, North Korea responded by calling the actions “state terrorism” and that the “chief culprit” involved in “cooking up the ‘sanctions resolution’, be beaten to death with a stick fit for a rabid dog”.
Japan is also threatened, as the hermit kingdom claims they will be “sunk into the sea by a nuclear bomb” and South Korea to be “severely punished and wiped out with fire”.
It follows satellite images that have been released indicating Kim Jong-Un has ambitions to continue his nuclear programme despite the sanctions.
The pictures were taken above the Punggye-ri nuclear test site in the north of the country.
Analysts for 38 North, who are devoted to reporting on the regime, believe this activity may indicate that preparation for future tests in other underground portals is underway.
The pictures apparently show a fresh crater, which may have been caused by the portal used for the hydrogen bomb test caving in after detonation, although 38 North said it was impossible to be certain.
Although experts have now concluded the latest nuclear test yielded an estimated 250 kilotons blast which is believed to be the maximum yield the Punggye-ri can contain.
NBC journalist Hans Nichols tweeted: “US intel has observed N Korea prepping for a possible missile test in coming days, per 3 mil officials. UN sanctions have not slowed program.”
Treasury Secretary Steve Munchin suggested on Wednesday that the US is willing to cut off trade “with anyone who trades with North Korea”.
He said in an interview on Fox News: “I’ve worked on an executive order that’s ready if the president wants to use it.
“We are going to be careful in using these tools, but the president is committed. We will use economic sanctions to bring North Korea to the table.”
When asked whether he included China, Mnuchin replied: “Stopping trade with anybody. Nobody would be off the table.”
