Anti-capitalist protesters marched through Chicago's State Street shopping corridor the day before the city was to host dozens of world leaders at the NATO summit.
Shoppers and tourists appeared puzzled by the demonstration early Saturday evening. Mounted police appeared at the end of the march, which blocked traffic at times. It was the latest stop during an hours-long march that took demonstrators down Michigan Avenue and to the memorial of a deadly workers' riot. At times protesters and police clashed as police tried to block certain streets.
The protest march started with a rally in a downtown plaza in support for three NATO demonstrators who face terrorism charges. The NATO summit starts Sunday..
