Parliament has passed tuition hikes in British schools, and students are not happy about it. Protesters lashed out against a car containing Prince Charles and his wife Camilla Thursday, though they drove away unhurt. Six police officers have been injured by throngs of protesting students, who are throwing stones and snooker balls and setting fires in Parliament Square. Nineteen people have been treated for injuries according to the London Ambulance Service. Three ministerial aides resigned in protest of the decision. Since the plan to drastically raise tuition fees was announced, students have occupied schools, and last month attacked the Conservative party headquarters.
