US joins global push against violent extremism online

Two years after a white supremacist in New Zealand livestreamed the slaughter of 51 Muslim worshippers on Facebook, French President  สล็อตxo Emmanuel Macron says the internet continues to be used by terrorists as a weapon to propagate hate.

Macron and other leaders from tech giants and governments around the world - including the U.S. for the first time - gathered virtually on Saturday to find better ways to stop extremist violence from spreading online, while also respecting freedom of expression.

It was part of a global effort started by Macron and New Zealand Prime Minister Jacinda Ardern after deadly attacks in their countries were streamed or shared on social networks.

The U.S. government and four other countries joined the effort, known as the Christchurch Call, for the first time this year. It involves some 50 nations plus tech companies including Google, Facebook, Twitter and Amazon, and is named for the New Zealand city where the slaughter at the two mosques took place.

British Prime Minister Boris Johnson said in a prerecorded video that authorities in his country alone had taken down more than 300,000 pieces of terrorist material from the internet over the past decade, which he described as a tsunami of hate.

"Terrorist content is like a metastasizing tumor within the internet, or series of tumors," Johnson said. "If we fail to excise it, it will inevitably spread into homes and high streets the world over."
