Five global technology companies have pledged to limit terrorist material online.

Axar.az reports citing BBC.

Facebook, Amazon, Google, Twitter and Microsoft will develop shared tools to detect and remove terrorist or extremist content among other measures.

The pledge was made at a Paris summit, which was called after the terror attack in Christchurch, New Zealand left 51 people dead.

The March attack was live-streamed on social media.

French President Emmanuel Macron hosted the event with New Zealand Prime Minister Jacinda Ardern, who has been calling for technology executives to sign a pledge as the "Christchurch Call".
