Facebook has started issuing warning notices over videos posted on the social networking site that their content might "shock, offend and upset" when viewed as the company faces repeated criticism over recent years for allowing violent and graphic images that it deems to be of public interest.
The alert also prevents the videos from automatically playing in the newsfeeds of users unless they are clicked unlike other clips, reported BBC.
Facebook is also preventing such videos to be played in front of users who are identified as below 18 years of age.
The company's safety advisors have initiated the move on the website.
The first post to be affected was the video that showed the footage of Charlie Hebdo suspect murdering a French police official.
