The UN's rights chief has warned that Donald Trump's statements pointed to a "dangerous" figure emerging on the world stage if he won the US presidency.
At a press conference in Geneva, UN High Commissioner for Human Rights Zeid Ra'ad Al Hussein said he was "not keen or intent on interfering in any political campaign".
But, he said, in light of the "unsettling" and "disturbing" comments from the US presidential candidate it was only right to sound the alarm.
"If Donald Trump is elected, on the basis of what he has said already, and unless that changes, I think that it is without any doubt that he would be dangerous from an international point of view," Mr Zeid said.
He referred to the Republican candidate's call to bring back interrogation techniques that legal experts say amount to torture.
And, he said, Mr Trump's attacks on "vulnerable communities" such as Muslims, immigrants and minorities "suggest that they may well be deprived of their human rights".
Earlier, US President Barack Obama said Mr Trump's comments on a 2005 videotape about groping women would disqualify him from even a job at a supermarket.
Speaking at a campaign rally in North Carolina for Hillary Clinton, Mr Obama said the choice was clear in the election even before the tape was leaked last week showing Mr Trump speaking crudely about women.

"Now you find a situation in which the guy says stuff that nobody would find tolerable if they were applying for a job at 7-Eleven," Mr Obama told the crowd, referring to the grocery chain.
Mr Trump said during Sunday night's presidential debate that he was embarrassed by the video, but dismissed it as "locker room talk."
Mr Obama also criticised some Republicans who have condemned the remarks but are still backing the New York businessman.
"The fact that now you've got people saying: 'We strongly disagree, we really disapprove ... but we're still endorsing him.' They still think he should be president, that doesn't make sense to me," Mr Obama said.

Earlier, White House spokesman Josh Earnest said the remarks in the recording amounted to sexual assault.
Mr Obama also took aim at Mr Trump's business credentials, referring to a New York Times report that showed he claimed a nearly €1 billion loss in one year on his taxes in the 1990s.
"They say the house always wins," Mr Obama quipped about Mr Trump, who was a casino developer at the time. "I don't know how that happens."
Meanwhile, Mr Trump has criticised US House Speaker Paul Ryan and other "disloyal" Republicans and vowed to campaign in whatever style he wants now that the party establishment has largely abandoned him.
It is so nice that the shackles have been taken off me and I can now fight for America the way I want to.

Despite winning the second debate in a landslide (every poll), it is hard to do well when Paul Ryan and others give zero support!

Mr Trump, in a barrage of Twitter posts, condemned the Republicans who have backed away from his White House run, deepening the rift in the party over his struggling campaign for the 8 November election.
"It is so nice that the shackles have been taken off me and I can now fight for America the way I want to," Mr Trump said, adding he would engage his Democratic rival on his own terms.
Describing "disloyal" Republicans as more difficult than Mrs Clinton, he said: "They come at you from all sides. They don't know how to win - I will teach them!"
'Get out and vote - November 28'
Mr Trump has urged his supporters to get out and vote - on the wrong date.
Speaking in Florida, he said: "We're doing something that's incredible it's a movement.
"But if we don't win. All it is, is a little asterisk in history.
"There's never been anything like this so go and register. Make sure you get out and vote. November 28."
Election day in the US is 8 November.
