Facebook has again pulled graphic videos of beheadings after an outcry.
The social network introduced a temporary ban on such videos in May, but announced on Tuesday that it would remove the block on the grounds that the site is used to share information about world events.
A spokeswoman for the website said at the time: "Facebook has long been a place where people turn to share their experiences, particularly when they're connected to controversial events on the ground, such as human rights abuses, acts of terrorism and other violent events. People are sharing this video on Facebook to condemn it. If the video were being celebrated, or the actions in it encouraged, our approach would be different."
But after a widespread outcry - including from Prime Minister David Cameron, who called their decision "entirely unacceptable", the site appears to have relented.
It has removed a specific video of a woman being beheaded in Mexico, and said it will use a wider set of criteria to judge individual videos in future.
"Based on these enhanced standards we have re-examined recent reports of graphic content and have concluded that this content improperly and irresponsibly glorifies violence. For this reason we have removed it."
It also admitted that its previous strategy was flawed, and said that it still wanted to promote an atmosphere of genuine open discussion.
It said in a statement:
""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," Facebook said in a statement.
"Second, we will consider whether the person posting the content is sharing it responsibly, such as accompanying the video or image with a warning and sharing it with an age-appropriate audience."
