Elon Musk has rejected claims that he helped incite disorder in Belfast, as UK ministers, Ofcom and Northern Ireland leaders said online posts helped fuel racist violence after a knife attack and subsequent unrest.

Elon Musk has rejected accusations that he helped incite disorder in Belfast, as the UK government, Ofcom and Northern Ireland leaders sharpened their response to violent unrest that followed a knife attack in the city.

The dispute has become the latest flashpoint in a wider debate over how quickly social media companies should remove illegal or harmful content during crises, and whether platform owners can be held responsible when online posts help spread violence and racist intimidation.

Musk denies blame

Musk said the problem was not social media or his own comments, but the UK’s immigration policy. His denial came as officials and regulators linked online commentary to disorder in Belfast that quickly spread beyond the original incident.

Ofcom said some of the violence appeared to have been incited online. The regulator’s assessment came alongside warnings from ministers and police that posts were helping circulate racist material, threats and details that could endanger people’s safety.

Disorder after the knife attack

The unrest began after a knife attack in north Belfast and escalated into violence and arson. Officials said the subsequent disorder was unjustified, with attacks on homes, vehicles and police.

The Police Service of Northern Ireland warned social media users that sharing address details about properties was putting lives at risk and could amount to a criminal offence. Police said the online spread of location details was increasing danger for people caught up in the unrest.

Northern Ireland justice minister Naomi Long condemned the violence as racist and unjustifiable. She said the disorder was stoked by online actors, reflecting local anger about the scale and impact of the unrest.

The family of the stabbing victim also appealed for calm, saying the unrest was not welcome. Their statement underscored the human toll of a dispute that has rapidly become a national political issue.

Government response

Prime Minister Keir Starmer condemned the violence in the House of Commons and vowed to crack down on people fuelling division online. His comments signalled that the Belfast disorder is now feeding directly into the government’s broader approach to online incitement.

Technology secretary Liz Kendall said the government would bring forward an update to the Online Safety Act next week to require faster removal of illegal content circulating during crises. She also said she had asked Ofcom to speak urgently with X and other platforms about compliance with the law.

That response points to a tighter crisis-period takedown regime, with ministers arguing that illegal content should not remain online long enough to worsen a public-order emergency.

What happens next

The immediate questions are whether the disorder will continue, whether Ofcom moves beyond warnings into formal enforcement action, and how quickly the government can advance changes to the Online Safety Act.

Officials are also expected to keep monitoring arrests, charges and any further attempts to exploit the unrest online. The Belfast violence has become a test case for how the UK handles the overlap between public disorder, online amplification and political blame.
