Tension continues to mount in Venezuela as the country prepares for a controversial vote Sunday that could rewrite its constitution.
A new wave of violent clashes between Venezuelan security forces and demonstrators this week added to the growing death toll.
As of Thursday, officials estimate more than 100 people had been killed in the months of political unrest.
The surge in violence prompted the U.S. government to get some of its citizens out of Venezuela.
The State Department issued a travel warning Thursday, citing the country's "social unrest, violent crime, and pervasive food and medicine shortages."
