LONDON — The British government has called on Elon Musk to act responsibly after the tech billionaire used his social media platform X to unleash a barrage of posts that officials say risk inflaming the violent unrest gripping the country.

Justice Minister Heidi Alexander made the comments Tuesday morning after Musk posted a comment saying that “Civil war is inevitable” in the U.K. Musk later doubled down, highlighting complaints that the British criminal justice system treats Muslims more leniently than far-right activists and comparing Britain’s crackdown on social media users to the Soviet Union.

“Use of language such as a ‘civil war’ is in no way acceptable,” Alexander told Times Radio. “We are seeing police officers being seriously injured, buildings set alight, and so I really do think that everyone who has a platform should be exercising their power responsibly.”

Britain has been shaken by violence for more than a week, as police clashed with crowds spouting anti-immigrant and Islamophobic slogans in cities and towns from Northern Ireland to the south coast of England. The unrest began after right-wing activists used social media to spread misinformation about a knife attack that killed three girls during a Taylor Swift-themed dance event on July 29.

Prime Minister Keir Starmer, who has described the riots as “far-right thuggery,” said after an emergency meeting with law enforcement officials and government ministers Tuesday that perpetrators will swiftly be punished.
