Anger over Christchurch video on social media

People worldwide are angry because a video of the killings at a mosque in Christchurch is still on social media sites. On Friday, a terrorist shot and killed 50 worshippers at two mosques. The gunman live-streamed the shootings on Facebook. The video spread across social media. Many people think social media companies have not done enough to remove the video. Social media users posted messages asking people to stop sharing it. One user said: "That is what the terrorist wanted." Another said social media sites quickly take down music videos but not terror videos.

Facebook said it acted quickly to remove the video. It said: "New Zealand Police alerted us to a video on Facebook shortly after the live-stream commenced. We quickly removed both the shooter's Facebook and Instagram accounts and the video." YouTube said it removes videos as soon as people highlight them. The UK's Home Secretary said social media sites must do more to stop the spread of "sick material" online. He said: "It is wrong and it is illegal." He said social media sites must not "do the terrorists' work for them". He said this terrorist wanted to spread his ideas.
