Vile rants by far-Right extremists celebrating the Finsbury Park attack were circulating on Facebook and Google last night.

Hate-filled fanatics also used social media networks to heap praise on the killer as a ‘hero’ who deserved a medal.

In one video, a man posing in front of a Nazi flag said he was ‘so happy right now’ because the English had ‘grown some balls’ and a white man had driven ‘into a bunch of Muslims’.

The American, who goes by the name ‘Jermania’, posted the video on Google’s YouTube website. In the clip, he said: ‘Greetings comrades, I am so happy right now. It’s turning out to be a wonderful Father’s Day.

‘I think the English have finally grown some balls and a white man, possibly – can’t say for sure yet – but someone has driven a van into a bunch of Muslims who were leaving a mosque. I think they [the English] finally ****ing hit back, and you know this is going to kick it off right here … about ****ing time. Well done.’

Google removed the video, saying ‘this kind of content has no place on YouTube’ and that it is ‘working with government, law enforcement and civil society groups to tackle the problem of violent extremism online’.

But it left dozens of other videos by the white supremacist, including others filmed in front of a Nazi flag. Some videos on YouTube even claimed the attack was fake.

One alleged the Grenfell Tower fire was also ‘100 per cent staged’.

It comes days after Google announced it would start using artificial intelligence to scan for hate speech.

Extremists branded the Finsbury Park killer a ‘top man’ on the Facebook page of far-Right group Britain First. Under a video entitled ‘Finsbury Park mosque terror attack – who is the suspected terrorist?’, a far-Right fanatic commented that ‘he is a b****y hero’.

On Twitter, one user wrote: ‘Let’s hope Finsbury is the first shot in a worldwide war on Islam and the invaders that bring it with them from third world.’

Another said: ‘History notes Finsbury Park attack as day when war on Muslim hatred and murders began. Government failed, people took charge.’

A video by English Defence League founder Tommy Robinson, first published before the attack, was also circulated on Twitter.

In it, he said a ‘disgruntled, angry population’ would ‘end up cleaning out this Islamic problem’.

Twitter declined to comment ‘for privacy and security reasons’. Last night, it took Daily Mail reporters seconds to find pro-Nazi messages on Twitter.

One hateful message claimed Hitler’s reputation had been unfairly tarnished.
