A North Korean state newspaper on Thursday called President Trump Donald John TrumpFederal prosecutor speaks out, says Barr 'has brought shame' on Justice Dept. Former Pence aide: White House staffers discussed Trump refusing to leave office Progressive group buys domain name of Trump's No. 1 Supreme Court pick MORE a "psychopath" and said that he was weighing a pre-emptive strike against the country to divert attention from political turmoil in the U.S., The Washington Post reported.

The commentary warns South Korea, a key U.S. ally in the region, against following the lead of "psychopath Trump," saying that doing so "will only lead to disaster."

It also suggests that Trump is facing a "tough situation" at home, including his possible impeachment, and is following in the footsteps of other U.S. presidents in escalating tensions to distract from domestic political trouble.

The commentary came three days after the death of Otto Warmbier, the American man who returned to the U.S. last week after being detained in North Korea for 17 months.

During his detention, details of Warmbier's condition remained unknown to his family and U.S. officials. Upon news of his return, he was revealed to have been in a coma since March 2016.

Warmbier's death has further raised tensions between the U.S. and North Korea, who have increasingly butted heads over Pyongyang's rapidly advancing nuclear and missiles programs.

In his first months in office, Trump sought to pressure China, Pyongyang's only major ally, to rein in North Korea and help stymie its weapons programs.

Trump, however, tweeted on Tuesday that seeking China's assistance in addressing North Korea "has not worked out."

While I greatly appreciate the efforts of President Xi & China to help with North Korea, it has not worked out. At least I know China tried! — Donald J. Trump (@realDonaldTrump) June 20, 2017

It wasn't clear exactly what the president meant by the tweet or whether he would continue to seek Beijing's cooperation on the matter.
