Facebook is facing legal action from a 14-year-old from Northern Ireland who claims not enough was done to stop a naked picture of her being repeatedly posted.

Lawyers for the teenager, who is from Belfast, say the image should have been blocked, but the website insists it does not have to do that under European law.

She is suing Facebook and the person who posted the photo – in what is believed to be the first case of its kind in the world.

It will now go to trial.
