Communities in northern Chile continue to experience a migrant crisis due to failures of the national government, the mayor of the border town of Colchane told Efe.

"It remains a very concerning issue for us because of the massive, uncontrolled influx. In recent days another victim was added to the list of fatalities and regrettably, all of the actions announced by the government have simply not worked," Javier Garcia said.

For decades, undocumented migrants have crossed into Chile's arid, sparsely populated north from neighboring Bolivia and Peru.
