A Jordanian prince has chimed into mounting criticism lobbed at Donald Trump .

Prince Zeid Ra’ad Zeid Al-Hussein, who serves as the United Nation's high commissioner for human rights, said the U.S. Republican candidate would be a "dangerous" president for the world, during a news briefing in Geneva this week.

“If Donald Trump is elected, on the basis of what he has said already and unless that changes, I think it’s without any doubt that he would be dangerous from an international point of view,” Hussein said, according to The Guardian .

Trump's presidential campaign has been characterized by blatant sexism and overt xenophobia. He has repeatedly targeted minority groups with his rhetoric and called for a ban on all Muslims  from entering the U.S.

Hussein called into question Trump's leadership abilities, pointing to the candidate's dishonesty.

"I always believe that it’s incumbent on leaders to lead and to lead in a way that is ethical and moral," Hussein said, when asked about Trump.

"The use of half-truths is a very clever political device. Because as every propagandist knows, you allow the listener to fill in the rest."

Hussein said he didn't want to interfere with "any political campaign within any particularly country," he said but felt compelled to voice his opinion in light of Trump's support for the use of torture and his "focus on vulnerable communities in a way that suggests that they may well be deprived of their human rights."

This isn't the first time Hussein criticizes Trump. In a scathing rebuke in The Hague last month, Hussein chastized Trump and other western right-wing politicians, going as far as to compare their ideology to that of ISIS.

"All seek in varying degrees to recover a past, halcyon and so pure in form, where sunlit fields are settled by peoples united by ethnicity or religion. A past that most certainly, in reality, did not exist anywhere, ever," he said, according to the BBC .

"Make no mistake, I certainly do not equate the actions of nationalist demagogues with those of Daesh (ISIS). But in its mode of communication, its use of half-truths and oversimplification, the propaganda of Daesh uses tactics similar to those of the populists."

Hussein reiterated this week that his main concern is for vulnerable communities, such as minority groups in society.

"We have to be on guard to see that in the end vulnerable populations, populations at risk do not again see their rights deprived because of a view that is in the ascendancy based on false premises," he said.
