The state news agency hit Biden over his age, saying that the 76-year-old is in “the final stage of dementia" and that the “time has come for him to depart his life."

“It was the last-ditch efforts of the rabid dog expediting his death,” KCNA said in a commentary. “Rabid dogs like Baiden [sic] 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.”

North Korea has in the past has lauded Trump for his dealings with Kim, as the two leaders have met three times during Trump's presidency to discuss improving bilateral relations and ending the North's nuclear program.

In May, North Korea also blasted Biden, calling the former vice president an "imbecile."

Andrew Bates, rapid response director for Biden's campaign, responded saying “it's becoming more and more obvious that repugnant dictators, as well as those who admire and ‘love’ them, find Joe Biden threatening."

"That's because he'd restore American leadership in the world on day one by putting our security, interests, and values at the heart of our foreign policy."
