Facebook to tighten live stream access after mosque attacks

Facebook on Friday said it is tightening live video streaming rules in response to the service being used to broadcast deadly attacks on mosques in New Zealand. The Christchurch attacks -- carried out by a self-avowed white supremacist who opened fire on worshippers at two mosques -- claimed 50 lives. Many people have "rightly questioned how online platforms such as Facebook were used to circulate horrific videos of the attack," chief operating officer Sheryl Sandberg said in an online post.
