The Amazonian ethnic groups which live in the Isiboro Secure territory, known by its Spanish acronym TIPNIS, are completing a 370 miles (595 km) march from Trinidad, in the northern Beni province, to La Paz to protest against a projected 185 mile (298 km) long highway that bisects the protected park in the Amazon forest, activists leading the march said. The protesters, who have a list of demands apart from their rejection of the highway project being financed by Brazil, are entering a rural region with strong sentiments for President Evo Morales, raising the possibility of confrontations on their way to La Paz. The march is on its 37th day. REUTERS/David Mercado"
