LONDON (AFP) - Thousands of anti-capitalist protesters calling for revolution scuffled with police in central London and outside Buckingham Palace on Wednesday after marching on parliament.

Part of a "Million Masks March" held in several world cities and organised by activist group Anonymous, the protesters tossed traffic cones, bottles and street signs at police and pulled down metal barricades.

The demonstration was held on the night of Britain's Guy Fawkes Night, and many of the marchers wore the white masks of the man who plotted to blow up parliament in 1605, now associated with Anonymous.

"One solution, revolution," the protesters chanted, some setting off fireworks as they faced off with lines of police.

Protesters also tried to storm national broadcaster the BBC, but were blocked from entering by police. Shops closed their doors as protesters broke off to march down London's central shopping district, pulling over bins and smashing a car window.

Ten protesters were arrested on suspicion of offences including assaults on police, obstruction and fireworks offences, police said.
