Social media platforms that incite violence and promote racism must be held accountable, campaigners demand.
In response to Monday night's knife incident, Belfast has seen a surge in violent unrest which set homes and vehicles on fire, and caused targeted racial attacks.
Naomi Smith, chief executive of Best for Britain, which campaigns against the radical right, said:
“This appalling violence - with innocent people’s homes being burned and lives being put at risk - is just the latest example of the consequences of the sickening far-right messaging and outright racism being stoked by the world’s richest man.
“The populists that incite violence and stoke division should face the full force of the law, not just those who took to the streets and committed violent acts. The Government should take immediate steps to hold X accountable for content posted on the site inciting violence in the UK, and at the very least should stop using X to communicate with voters.”
