Thousands of Venezuelans poured into the main streets of Caracas on Wednesday, with rival camps demonstrating support for and against President Nicolas Maduro and his socialist policies.
Two Venezuelan students and a National Guard sergeant died after being shot during protests, according to Reuters.
The deaths mean eight people have now been killed during protests in Venezuela this month.
In Washington, administration officials are worried the Venezuela government is working to suppress the opposition.
“We are concerned that the government of Maduro is violating its own constitution and is not allowing the opposition to have their voices heard, nor allowing them to organize in a way that expresses the views of the Venezuelan people,” U.S. Secretary of State Rex Tillerson said Wednesday at the State Department.
