Facebook has said it will delete videos of people being decapitated which had been spread on its site.
"We will remove instances of these videos that are reported to us while we evaluate our policy and approach to this type of content," it said.
The news came less than two hours after the BBC revealed a member of Facebook's own safety advisory board had criticised its stance.
The social network had previously refused to ban the clips.
It had said people had a right to depict the "world in which we live".
