Menlo Park, USA-Facebook has removed a video clip showing a woman’s decapitation and issued new rules about what can be shared on its site. The U-turn comes two days after the BBC revealed the firm had dropped a ban on clips showing extreme violence. That move was criticised by the British prime minister and the company’s own safety advisers. Facebook now says it will still allow some graphic content but will take a more comprehensive look at its context. It outlined its revised policy in a press release. “First, when we review content that is reported to us, we will take a more holistic look at the context surrounding a violent image or video, and will remove content that celebrates violence,” it said.
