Ecuador has brought in new rules to stop Venezuelan migrants entering the country without a passport, leaving many stranded in neighbouring Colombia.
Thousands of Venezuelans fleeing their country’s economic and political crisis have been crossing into Ecuador from Colombia using only identity cards.
Most are heading south to join family members in Peru and Chile.
Colombia has protested against the move, saying vulnerable people will be trapped on its side of the border.
In a separate incident, residents of a Brazilian town attacked a Venezuelan migrant camp yesterday and drove the occupants back across the border.
Venezuela has suffered for years from high inflation and the chronic shortage of food and medicines.
