US President Donald Trump reiterated his complaints on ​Friday about not receiving the Nobel Peace ‌Prize, calling it a disgraceful and embarrassing decision that had left a stain on Norway, which hosts the Nobel committee.

Trump ​unleashed on Norway hours after the committee ​awarded this year's prize to Navi Pillay, a former ⁠International Criminal Court judge who oversaw a UN ​report that concluded Israel committed genocide in Gaza.

Trump called ​Pillay a "mystery person" during a campaign rally in Syracuse, New York. "I never heard of the person. Nobody did."

Each year of his ​presidency, Trump has expressed disappointment at his failure ​to win the prize.

"This is an indelible stain on the ‌country ⁠of Norway and those people that made such a disgraceful and embarrassing decision," Trump said.

He listed a number of conflicts that he claimed a role in resolving ​and said he ​has helped ⁠prevent wars from breaking out between North and South Korea, Japan and North ​Korea, and China and Taiwan, without providing ​evidence.

"The ⁠Nobel Peace Prize has been forever discredited by a handful of radical ideologues who are anti-democracy and really ⁠enemies ​of civilization. And we will ​not forget, Norway," he said.
