Thousands of angry students took to the streets of London Thursday for another protest, as British lawmakers voted on controversial plans to raise tuition fees up to 9000 pounds.Tens of thousands of students from across the UK were expected to converge on the capital, according to the National Union of Students (NUS), with most marching towards Westminster, where the country's parliament building is located. Hundreds of police officers were deployed, many with riot gear, as the authorities looked to avoid a repeat of the disturbances last month when hundreds of protesters stormed the Conservative Party headquarters in the city. The Conservatives are the senior partner in a ruling coalition with the Liberal Democrats.
