The police have made no move to advance on the demonstrators, they are apparently trying to hold a fixed line and let the clouds of tear gas do their work for them. The demonstrators have retreated in order to have a discussion out of the gas. They believe that their original estimate of a 12km march was incorrect, and that they are only about 1km away from the crucial junction that they want to block. As the group moved to have a decision-making assembly, protestors erected barricades on the road to deter the police.
