British Prime Minister David Cameron on Thursday condemned violence that erupted during a demonstration against government plans to triple university fees, and police acknowledged they were unprepared for the mayhem.
Cameron said "the full force of the law" should be used against protesters who smashed windows, lobbed projectiles and stormed a London office tower housing the headquarters of his Conservative Party.
"People long in our history have gone to marches and held banners and made protests and made speeches and that's part of our democracy," Cameron said in Seoul, South Korea, where he is attending a G20 summit.
"What is not part of our democracy is that sort of violence and lawbreaking. It's not right. It's not acceptable and I hope that the full force of the law will be used."
