An anti-Islamic video retweeted by President Donald Trump of a boy being beaten up by a ‘Muslim migrant’ has been ironically dismissed as fake news by police in the Netherlands.

The video, which was initially posted by Britain first deputy leader Jayda Fransen and then retweeted by Trump, has been confirmed to be six months old and was filmed in Monnickendam, ten miles north of Amsterdam, police said.

A Monnickendam Police spokeswoman told MailOnline: ‘The guy in the video attacking a boy on crutches is a Dutch national.’

Dutch newspaper De Telegraaf also quoted sources saying the attacker was “not a Muslim, let alone a migrant”.

Trump received a backlash after he retweeted three videos from Britain First deputy leader Jayda Fransen, who has been convicted of hate crimes, which showed ‘Muslims’ engaging in bad deeds.

One of those videos has now been proven to be ‘fake news’.

The other two posts including footage of a Muslim man ‘destroying a statue of Virgin Mary’ and a video showing a ‘Muslim’ mob throwing a teenage boy off a roof, are at least five years old.

The white house dismissed any wrongdoing on Trump’s behalf and said although the videos might be fake, the threat is real.

President Trump’s spokesperson Press Secretary Sarah Huckabee Sanders told journalists.:’Whether it is a real video, the threat is real,’

‘That is what the president is talking about, that is what the president is focused on dealing with, those real threats and those are real no matter how you look at it.’

Theresa May has since called Mr Trump “wrong” for endorsing the inflammatory, unverified tweets.

Trump responded on Twitter, to the wrong Theresa May, saying: “Theresa @theresamay, don’t focus on me, focus on the destructive Radical Islamic Terrorism that is taking place within the United Kingdom. We are doing just fine!”
