"In the first 24 hours we removed 1.5 million videos of the attack globally, of which over 1.2 million were blocked at upload...," Facebook said in the tweet.

Facebook said it's also removing all edited versions of the video that don't show graphic content. This is being done, a New Zealand Facebook spokeswoman said, "out of respect for the people affected by this tragedy and the concerns of local authorities."
