LONDON - Facebook said on Wednesday it banned Britain First from its platform for breaking rules against inciting hatred, blacklisting a far-right group brought to global attention when U.S. President Donald Trump retweeted its anti-Islamic posts.

Facebook said it had taken down Britain First's Facebook page and those of its leaders, Paul Golding and Jayda Fransen, for repeatedly violating rules designed to stop the incitement of hatred against minority groups.

A fringe party, British First shot to the fore last November when Trump sparked outrage in Britain and a sharp rebuke from Prime Minister Theresa May for retweeting British far-right anti-Islam videos.

The removal of the Britain First pages comes as Facebook and other internet firms like Twitter and Google are under growing pressure to police their networks, refereeing content to prevent extremist groups spreading their messages and recruiting online.

Facebook said it was careful not to remove posts or pages just because they were controversial and some people didn't like them, but said that Britain First had gone further and broken its anti-hatred rules with its anti-Islam posts.

"We do not do this lightly, but they have repeatedly posted content designed to incite animosity and hatred against minority groups, which disqualifies the pages from our service," Facebook said in a blog post.
