Facebook says a livestream of last week's New Zealand mass shooting was viewed fewer than 200 times during its live broadcast and that nobody reported the video to Facebook while the livestream was ongoing.

"The first user report on the original video came in 29 minutes after the video started, and 12 minutes after the live broadcast ended," Facebook VP and Deputy General Counsel Chris Sonderby wrote in an update posted yesterday.
