Venezuelan riot police have used tear gas and rubber bullets in an attempt to break up thousands of demonstrators in Caracas.
They tried to stop the march reaching a key road, then edged back slightly as masked protesters threw stones and Molotov cocktails.
Eight people have died in the past three weeks of violent protest against President Maduro.
