World leaders wrangled Wednesday on how a London summit could fix the global economy as demonstrators attacked a bank in an anti-capitalist riot in the British capital

Demonstrators laid siege to the Bank of England and smashed the windows of a nearby bank that has become a symbol of the financial crisis rescue carried out by the British government which will be discussed at Thursday's Group of 20 summit in the city.

Several thousand invaded the main financial district and tensions spilled over when protesters smashed their way into a major branch of Royal Bank of Scotland, which was state-owned last year.
