Facebook said a live streamed video apparently showing last week's attack on two mosques in New Zealand was viewed 4,000 times before it was removed.

The suspected gunman, an Australian named Brenton Harrison Tarrant, allegedly killed 50 people after opening fire on Muslim worshipers at the two mosques, livestreaming the whole ordeal on Facebook. Tarrant has been charged with murder.
