Only a few hours before the opening of the G20 summit in Toronto, protesters clashed violently with police.
More than 10,000 anti-G20 protesters marched into Toronto's financial district after veering off a planned protest route. At that time, more radical elements in the march smashed the windows of shops and banks and burned two police cars. At least two protestors have been arrested and three were injured.
The police closed part of Toronto's subway system along the march route. Canada is spending more than 1.2 billion Canadian dollars on security and there have been 40 summit-related arrests since June 18th. The police remain on alert for further violence.
