Brazilian President Michel Temer has announced plans to send troops to Brazil’s border with Venezuela to deal with the growing number of refugees entering Brazil.

President Michael Temer: “I decree today the use of the armed forces to guarantee law and order in Roraima state, naturally to offer security to Brazilian citizens and to the Venezuelan immigrants who are fleeing their country in search of shelter in Brazil.”

According to the United Nations, more than 1.6 million Venezuelans have fled the country since 2015, with most going to Brazil, Colombia, Peru and Ecuador. Venezuela is facing food shortages amid skyrocketing inflation caused in part by crippling U.S. sanctions, which have cut off Venezuela from billions of dollars of potential loans and some of its oil revenue.
