Students attack Prince Charles' car after fee hike

Furious student protesters attacked a car carrying Prince Charles and his wife, Camilla, vandalized buildings and battled riot police Thursday as a controversial hike in university fees triggered Britain's worst political violence in years.

In a major security breach, demonstrators set upon the heir to the throne's Rolls Royce as it drove through London's busy West End on its way to a theater. A group of up to 20 struck it with fists, sticks and bottles, breaking a window and splattering the gleaming black vehicle with paint.

In the frenzy, some chanted "off with their heads!"

Adnan Nazir, a 23-year-old podiatrist who was following the protesters, said Charles, 62, kept his calm, gently pushing his 63-year-old wife toward the floor to get her out of the line of fire.

"Charles got her on the floor and put his hands on her," Nazir said. "Charles was still waving and giving the thumb's up.

"It was just a surreal thing," he said. "It was completely manic."

Charles' office, Clarence House, said the royal couple was unharmed. But the attack took police completely by surprise and raises serious security questions.

The chief of the Metropolitan Police, Paul Stephenson, said the force would launch an investigation into Thursday's violence.

Prime Minister David Cameron said the violence against the royal couple was "shocking and regrettable."

"It is clear that a minority of protesters came determined to provoke violence, attack the police and cause as much damage to property as possible," Cameron said. "They must face the full force of the law."

Police said it was unclear whether the royals had been deliberately targeted, or were simply in the wrong place at the wrong time.

The couple arrived looking somber but composed at the London Palladium theater, where they were attending a Royal Variety Performance.

Camilla later managed to shrug off the ordeal, saying there was "a first time for everything," the Press Association news agency reported.

Protesters erupted in anger after legislators in the House of Commons approved a plan to triple university fees to 9,000 pounds ($14,000) a year.

As thousands of students were corralled by police near Parliament, some strummed guitars and sang Beatles songs — but others hurled chunks of paving stones at police and smashed windows in a government building.

Another group ran riot through the busy shopping streets of London's West End, smashing store windows and setting fire to a giant Christmas tree in Trafalgar Square.

Police condemned the "wanton vandalism." They said 43 protesters and 12 officers had been injured, while 22 people were arrested. Police said the number of arrests would likely rise.

Home Secretary Theresa May said that "what we are seeing in London tonight, the wanton vandalism, smashing of windows, has nothing to do with peaceful protest."

The violence overshadowed the tuition vote, a crucial test for governing Conservative-Liberal Democrat coalition, and for the government's austerity plans to reduce Britain's budget deficit.
