On 13 May 2016 a state of emergency was declared in Venezuela by President Nicolás Maduro. The details of this emergency condition were not explained by Maduro but he mentioned conspiracy within the country and from an OPEC country and the United States to overthrow the Caracas government. The last state of emergency occurred in 2015 due to issues near the Colombian border, resulting in the suspension of constitutional guarantees and the Venezuela–Colombia migrant crisis.
