Dozens of activists have raised a multicolored, makeshift tent city in Bogota's main square to demand the government and rebels save a deal meant to end a half century of conflict — part of a belated outburst of activism across the country by Colombians stunned at last week's unexpected defeat of the peace accord in a referendum.

The mostly youthful demonstrators at what's called the "Peace Camp" reject any political affiliation. Organizers say their only goal is to make sure the peace deal signed last month by the government and rebels isn't scuttled.

The first two tents were raised Oct. 5 after as many as 25,000 people poured into the streets of Bogota to back the rejected accord. Within a week, the impromptu encampment has grown to 70 tents.
