Facebook says it's working on new ways to keep users from stumbling across gruesome content on its website following an outcry over the discovery of beheading videos on the site.
The controversy which has drawn in British Prime Minister David Cameron illustrates the difficulty of setting a universal standard across the 1 billion-user social network.
Facebook banned beheading videos in May but recently lifted the prohibition. Cameron, whose right-leaning government has unveiled a range of initiatives to censor objectionable content online, said today that allowing the videos back on the site was "irresponsible."
Facebook said in a statement that it is working on ways to warn people about the content they might see.
