"It's horrible," says Cristian, a Venezuelan migrant, frustrated at the blockade of the Desaguadero border crossing, which connects Peru and Bolivia. Blockades erected amid the political crisis in Peru have made life difficult for both locals and migrants, making it hard to obtain basics like food and fuel, or to pay for rent and other services. Seven Haitian migrants have died this year in the Andean highlands of Peru as their efforts to cross into Bolivia have been stymied by protests against the Lima government, according to the UN. The Haitians fell victim to a combination of factors: difficult access to food, shelter and supplies, and temperatures -- at an altitude of 3,800 meters (12,500 feet) -- sometimes near freezing.
