Facebook is tightening its rules around live-streaming in direct response to the Christchurch terror attack.

Tech giants and world leaders will soon meet at a summit in Paris to discuss how best to prevent extremism on social media.

The global call to action comes after the Christchurch gunman broadcast the mosque shootings live on Facebook on 15 March.

In a statement, Facebook said people who had broken certain rules on the platform would be temporarily banned from its livestreaming service.

"From now on, anyone who violates our most serious policies will be restricted from using Live for set periods of time - for example 30 days - starting on their first offense," a Facebook spokesperson said.

"We recognize the tension between people who would prefer unfettered access to our services and the restrictions needed to keep people safe on Facebook.

"Our goal is to minimize risk of abuse on Live while enabling people to use Live in a positive way every day."

Facebook also announced it would put $7.5 million into research to improve video analysis technology.
