DENVER (AP) - There were about 100 arrests after demonstrators clashed with police near the site of the Democratic Convention last night.

The confrontation erupted as police tried to break up a crowd interfering with traffic near the Denver City and County Building.

AP Television News video showed one group of protesters counting down from 10 and then charging at police. They quickly retreated as police shoved them back.

Some of the protesters threw bags containing a colored liquid. Police fired pepper spray.

Two of the protesters describe themselves as anti-capitalists who were protesting ecological devastation.
