ROTHERHAM, England — A ferocious mob of more than 460 masked rioters launched a savage assault on two hotels housing asylum seekers Friday evening, smashing barricades, crushing police lines, and plunging entire streets into chaos.

The violence erupted at 5:10 p.m. local time, turning what began as a protest over undocumented immigration into what officials are calling the worst coordinated hotel attacks in a decade.

Within minutes, police officers were retreating under a hail of bricks, fireworks, and raw fury. Six elite police units became trapped and were forced to withdraw as the mob overran their positions.

“This was not a protest,” said South Yorkshire Police Chief Constable Lauren Poultney in a late-night briefing. “This was organized, premeditated violence designed to terrorize vulnerable people.”

The attacks unfolded simultaneously in Rotherham and Tamworth — two towns that have become flashpoints in Britain’s increasingly volatile debate over migration and housing.

Witnesses described scenes reminiscent of a war zone. Storefronts were gutted. Emergency teams were overrun. A hotel in Rotherham was set partially ablaze before firefighters could force their way through the mob.

One rioter, his face obscured by a balaclava, shouted into a phone camera: “We’ve had enough — send them back before more British blood is spilled!”

Another, hurling a firework toward a line of riot shields, yelled: “Starmer sold us out — migrants get hotels, we get fear!” The reference to Prime Minister Keir Starmer underscored the deep political anger fueling the unrest.

Inside the targeted hotels, asylum seekers — many fleeing war and persecution in Afghanistan, Syria and Eritrea — huddled in stairwells as windows shattered around them.

“This is not Britain,” whispered one young man from Sudan, speaking through a cracked window before being evacuated by police. “We came here to be safe.”

The government has been scrambling to house more than 50,000 asylum seekers awaiting decisions on their claims. Hotel accommodations, costing taxpayers more than £8 million a day, have become a lightning rod for public anger.

Friday’s riots did not emerge from nowhere. For weeks, far-right groups have circulated fliers in Rotherham and Tamworth accusing migrants of driving crime and overwhelming local services — claims repeatedly debunked by official data.

According to the Office for National Statistics, knife crime in both towns has remained flat or declined over the past 18 months. But perception, in this inflamed atmosphere, has long since parted ways with reality.

Prime Minister Starmer condemned the violence in a televised address Saturday morning, calling it “an assault on British values” and vowing to deploy additional police units to prevent further outbreaks.

“I will not allow a mob to decide who belongs in this country,” Starmer said. “The rule of law will be upheld — no matter how many masks they wear.”

But the political damage is already spreading. Opposition leader Kemi Badenoch accused the government of “losing control of the streets,” while Reform UK leader Nigel Farage called the riots “a consequence of 10 years of failed immigration policy.”

As dawn broke over Rotherham, police had arrested 87 suspects. More arrests are expected. But the deeper question — how to restore order without inflaming an already combustible population — remains unanswered.

Britain has seen riots before: the 2011 London fires, the 2024 Bristol clashes. But Friday’s assault on migrant hotels marks something new: organized, multi-city violence explicitly targeting the most vulnerable.

One thing is clear. The fuse has been lit. And no one in Westminster yet knows how to snuff it out
