Facebook has resumed allowing videos containing graphic content, including decapitations, to be posted on its website.
The social media website lifted a temporary ban it had placed earlier this year on content featuring graphic violence.
Following a BBC report Facebook said gory photos and videos are permitted on its site so long as the content was posted in a manner intended for its users to "condemn" the acts rather than celebrate them.
Earlier this year, Facebook placed a temporary ban on content with graphic violence as it examined its policy in the wake of complaints about certain images posted on the website.
"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," the company said in a statement.
"People share videos of these events on Facebook to condemn them. If they were being celebrated, or the actions in them encouraged, our approach would be different."
Facebook said it was working on developing new ways to let users control what content they see, including advance warnings that particular images contain graphic violence.
The BBC reported that many Facebook users were complaining about a video on the site showing a masked man killing a woman in Mexico.
Facebook's current community standards forbid users from posting information that is threatening to others, as well as content that includes hate speech or is sexually explicit.
Groups with a record of violence or criminal activity are not allowed to maintain a presence on the site and Facebook said that "sharing any graphic content for sadistic pleasure is prohibited".
