ROUGH CUT (NO REPORTER NARRATION)<br/> STORY: A largely peaceful protest in the heart of London's financial district turned violent on Saturday (October 15), as tension between demonstrators and police began to escalate.<br/> Up to three thousand people were gathered near to London's stock exchange for a protest over economic inequality that organizers hope will match New York's 'Occupy Wall Street' movement.<br/> But organizers said one thousand of their number are trapped inside a tight police cordon in the immediate vicinity of St Paul's Cathedral, under a controversial police tactic known as "kettling".<br/> For more than a month demonstrators have occupied New York's Zuccotti Park, near the city's financial center of Wall Street, often leading to clashes with police.<br/> Throughout the day worldwide protests have sprung up in countries from New Zealand to Taiwan, in part a response to calls from the New York demonstrators for more people to join them.
