US election: Trump presidency 'dangerous', says UN rights chief
Donald Trump's "deeply unsettling and disturbing" views make him a danger internationally, the UN's human rights chief has said.
UN High Commissioner for Human Rights Zeid Raad al-Hussein cited Mr Trump's comments on the use of torture and his attitude to "vulnerable communities".
The Republican presidential candidate's campaign has been marked by a number of controversial comments.
Recent crude remarks about women have caused the biggest political fallout.
Overnight President Barack Obama, at a rally for Democratic candidate Hillary Clinton, condemned those comments, saying: "The guy says stuff that nobody would find tolerable if they were applying for a job at 7-Eleven."

Mr Hussein said at a news briefing in Geneva: "If Donald Trump is elected on the basis of what he has said already - and unless that changes - I think it is without any doubt that he would be dangerous from an international point of view."
Mr Hussein said he was "not keen or intent on interfering in any political campaign within any particular country".
But he said that when an election could result in an increase in the use of torture "or the focus on vulnerable communities in a way that suggests that they may well be deprived of their human rights, then I think it is incumbent to say so".
Mr Hussein has spoken out before on Mr Trump's policies, saying in June that "bigotry is not proof of strong leadership", while in September he launched a scathing attack on Western populist politicians, branding them "demagogues and political fantasists".
During the campaign, Mr Trump has said that "torture works" and has promised to bring back "a lot worse than waterboarding".
Waterboarding and other harsh interrogation techniques previously used by US forces on terror suspects have been banned by the Obama administration.
Mr Trump said of waterboarding in June: "I like it a lot. I don't think it's tough enough."
His comments on migrants, Mexicans in particular, have drawn fire from rights activists.
He has vowed to build a wall along the Mexican border and in June 2015 branded some Mexican migrants "rapists" and "murderers".
Mr Hussein's latest comments are unlikely to change the New York billionaire's harsh criticism of the United Nations.
"The United Nations is not a friend of democracy," Mr Trump said in March. "It's not a friend even to the United States of America, where as we all know, it has its home."
He has criticised the US spending on the organisation. In April, he said: "Where do you ever see the United Nations? Do they ever settle anything? It's just like a political game. The United Nations - I mean the money we spend on the United Nations."
Mr Trump is still battling the fallout from his lewd comments on women in a 2005 video released on Friday. Mr Trump described how he had sought to have sex with a married woman and made other sexually aggressive comments.
Many top Republicans, including House Speaker Paul Ryan, have since distanced themselves from Mr Trump.
Mr Trump fired back in a string of tweets, saying the "shackles" had been removed, allowing him to "fight for America the way I want to". He said he neither wanted nor needed Mr Ryan's support.
Mr Trump said "disloyal" Republicans "come at you from all sides. They don't know how to win - I will teach them!"
Mr Obama weighed in against Mr Trump at a campaign rally in Greensboro, North Carolina.
He said: "You don't have to be a husband or a father to say that's not right. You just have to be a decent human being."
Mr Obama questioned how senior Republican politicians could still want Mr Trump to be president.
Meanwhile Mr Trump delivered a gaffe while addressing supporters in Florida on Tuesday, telling them to go out and vote on the wrong date.
ABC News footage showed him saying: "Go and register. Make sure you get out and vote, November 28." The election is on 8 November.
A recent PRRI/Atlantic poll suggested Mrs Clinton holds a 49-38 lead over her opponent.
