CHICAGO - Four police officers were injured and 45 demonstrators arrested after baton-wielding police clashed with anti-war protesters marching on the NATO summit in Chicago on Sunday, police said.
A lawyer's group assisting protesters challenged police figures, saying at least 12 protesters were hurt, some with head wounds from police batons, and more than 60 people detained.
The confrontation began after a 2 1/2 mile march from a Chicago park to near the site of the summit, where leaders of the NATO alliance are discussing the war in Afghanistan.
Chicago Police Chief Garry McCarthy defended police tactics.
