Tech giants vow to step up fight

A global working group set up by Facebook, Twitter, YouTube, and Microsoft to remove extremist content will become an independent watchdog working "to respond quicker and work more collaboratively to prevent" attacks like Christchurch, New Zealand Prime Minister Jacinda Ardern said on Monday.

Ardern has pushed for stronger action since New Zealand's worst peacetime mass shooting in March, when a gunman attacked Muslims attending Friday prayers in Christchurch. He killed 51 people and broadcast the attack live on Facebook.

"In the same way that we respond to natural emergencies like fires and floods, we need to be prepared and ready to respond to a crisis like the one we experienced," Ardern told reporters on the sidelines of the annual United Nations gathering of world leaders.

The Global Internet Forum to Counter Terrorism was created in 2017 under pressure from US and European governments after a spate of deadly attacks. It will now become an independent organization led by an executive director, funded by Facebook Inc, Google's YouTube, Twitter Inc and Microsoft Corp.

Speaking at a joint news conference with Facebook Chief Operating Officer Sheryl Sandberg, Ardern said the organization would be governed by an operating board made up of company representatives and would have an independent advisory committee composed of government and civil society members.
