The secretive state of North Korea has launched an unexpected foul mouthed tirade on US Presidential candidate and former US Vice President Joe Biden.

In a series of insults, posted by the Nation’s official news agency, the KCNA, they called Biden a ‘rabid dog’ who must ‘be beaten to death” for insulting their leader, Kim Jong Un.

Biden has been very critical of Donald Trump’s summit with North Korea’s supreme leader Kim Jong-Un in the past, so maybe that is the reason why the unexpected foul mouthed tirades were launched against Biden yesterday, Friday.

At a campaign rally in Philadelphia back in May, Biden, a front runner for the presidential ticket of the Democratic party, accused Trump of ’embracing dictators and tyrants like Putin and Kim Jong-un’.

In a commentary on KCNA, the secretive state blasted Biden, ‘Such a guy had the temerity to dare slander the dignity of the supreme leadership of the DPRK,’ using the North’s official name, the Democratic People’s Republic of Korea.

It was the last-ditch efforts of the rabid dog expediting his death, reports circulating.

‘Rabid dogs like Baiden can hurt lots of people if they are allowed to run about. They must be beaten to death with a stick, before it is too late.’

Meanwhile North Korea has praised Trump so many times using the KCNA, saying how a ‘close personal relationship’ between Kim and Trump saved ties between their countries, and prevented both nations from going to war.
