US presidential hopeful Donald Trump says British Muslims are "absolutely not reporting" suspected terrorists, as he pledged to "hit Isis so hard you wouldn't believe it" if he becomes president.
Speaking to Good Morning Britain, he described the Brussels attacks as "outrageous", adding it was a "disgrace" that it was allowed to happen.
They're protecting each other but they're really doing very bad damage, they have to open up to society and report the bad ones.
Trump described yesterday's attacks as "retribution" for the arrest last week of Salah Abdeslam, who helped plot November's Paris attacks, and described parts of Brussels as an "armed camp".
"What's going on there and what's going on in many other locations like Paris and others is a disgrace, an absolute disgrace that we allow it to happen," he said.
[Salah Abdeslam] was in his neighbourhood, where he grew up, and nobody even turned him in. Many people knew he was there and yet he was the number one wanted fugitive in the world. He was there and everybody from that area knew he was there, nobody turned him in. There's something going on and there's something wrong.
Trump's claims "just not true"
But Muslim Council of Britain representatives disputed Trump's claim, labelling it "just not true".
Miqdaad Versi, assistant secretary-general, said he could not speak for the rest of Europe but in London it is "not the case", adding that there is a "much more integrated society" in the UK.
Mr Versi also warned that bigotry against Muslims is growing, describing it as a "serious concern".
Republican hopeful Trump sparked an outcry last year when he pledged to ban Muslims from the USA.
He also said that there was a "massive Muslim problem" in Britain.
But he told GMB's Piers Morgan that he was not anti-Muslim, adding: "I have great respect for Muslims, I have many friends that are Muslims."
