A group organized to resist the forthcoming G-20 summit in Pittsburgh announced plans for an unsanctioned mass march from Lawrenceville to the David L. Lawrence Convention Center on the first day of the meeting, setting up the possibility of a clash with police.

 

Such actions would be the first sizable test of such groups since last September, when plans to disrupt the Republican National Convention were themselves disrupted after anarchist groups were infiltrated by state and federal agents. Eight presumed leaders of the planned disruptions were arrested prior to the beginning of the convention.
