Facebook has removed the pages of the anti-Islamic group Britain First and its leaders.
The social media company said the group had repeatedly violated its community standards.
Earlier this month, Britain First's leader and deputy leader, Paul Golding and Jayda Fransen, were jailed after being found guilty of religiously aggravated harassment.
It is understood the offending posts included:
- a photo of the group's leaders with the caption "Islamophobic and Proud"
- a caption comparing Muslim immigrants with animals
- multiple videos posted deliberately to incite hateful comments against Muslims
Twitter suspended the accounts of Paul Golding and Jayda Fransen, after its new anti-abuse rules came into force last December.
US President Donald Trump had retweeted anti-Islamic videos posted by Fransen the previous month.
