Thousands of activists took part in an anti-NATO demonstration in
Chicago, where the military bloc's summit kicked off on Sunday. The
protest descended into clashes with police and at least 60 people were
arrested.

The clashes occurred as the demonstrators were trying to push their way through a police line to the site of the meeting.

Police
estimated the crowd on Sunday to be 2,500 to 3,000, though it appeared
that more turned out onto the streets of the city to voice their
opposition to NATO's wars.
