Colombia and Brazil have tightened border controls with Venezuela as both nations deal with a big influx of hundreds of thousands of migrants from their neighbour.
Colombian President Juan Manuel Santos said his government would implement stricter migratory measures and suspend new daily entry cards for Venezuelans, as well as deploy 3,000 new security personnel, including 2,120 more soldiers, along the frontier.
Brazil also announced that it would double its troops to patrol frontier regions, and would start relocating Venezuelans to towns and cities in its interior.
Both countries said they would take measures to count the number of Venezuelan migrants – Brazil through a census and Colombia through a registry – many of whom have entered their territory after fleeing a major economic and political crisis.
An estimated 550,000 people have arrived in Colombia without papers, and that number could reach one million by July, according to official forecasts.
Brazil has received around 40,000 Venezuelans in its northernmost state, Roraima. Last year, three United Nations-supported shelters filled amid increasing arrivals.
