Republican US presidential frontrunner Donald Trump has refused to take back claims he saw Muslims cheering in New Jersey after the 11 September attacks in 2001, despite a lack of proof.
He has drawn sweeping condemnation after saying earlier this month that Arab and Muslim Americans had publicly rejoiced the unprecedented terror attacks on the United States.
"It was 14 years ago but I saw it on television, I saw clips and so did many other people," Mr Trump told NBC's Meet the Press talk show.
"I've had hundreds of phone calls to the Trump organisation saying, 'We saw it. It was dancing in the streets'."
Within days of the attacks, police, fact-checkers and US media debunked the rumours that people were cheering from rooftops of Jersey City, across the river from Manhattan.
However, Mr Trump stood by his comments today: "I saw it. So many people saw it... And so why would I take it back? I'm not going to take it back."
Mr Trump has cited an article written by The Washington Post at the time saying authorities detained "a number" of people supposedly seen cheering in New Jersey.
But there was no indication in the article of thousands or even hundreds of Muslims cheering.
Mr Trump told Meet the Press that "we're looking for other articles and we're looking for other clips and I wouldn't be surprised if we found them," he said.
"But for some reason they're not that easy to come by."
