Three Venezuelans have died from gunshot wounds during protests against socialist President Nicolás Maduro, witnesses and local media have said, pushing the death toll to 34 from almost two months of demonstrations that have been answered with deadly force from both security forces and armed pro-government gangs.

Troops briefly clashed with a small group of protesters who attempted to block a highway in an upscale neighborhood of Caracas after thousands of opposition supporters marched to demand the release of students imprisoned during the unrest.

Demonstrators complaining of soaring prices and product shortages have vowed to remain in the streets until Maduro resigns, although there are few signs that the country’s worst turmoil in a decade will force him from office.

Argenis Hernandez, 26, was shot in the abdomen as he was demonstrating near a barricade in the central city of Valencia and died early on Saturday in a nearby hospital, according to local media reports.
