Facebook says it has deleted more than 1.5 million copies of the video of the mosque attacks in New Zealand in the first day after the incident.
In a tweet, it said that 1.2 million of those copies were blocked while they were being uploaded.
Fifty people died and dozens were injured in Friday’s twin shootings.
Facebook said it would also remove edited versions, to stop “graphic content” being shared, although copies still appear to be available online.
The social network released the information as politicians and commentators called for more to be done to police live-streaming.
New Zealand Prime Minister Jacinda Ardern said that Facebook and other social media giants had “further questions” to answer about how they responded to the event.
“Obviously these social media platforms have wide reach,” she said. “This is an issue that goes well beyond New Zealand.”
