Troops in Venezuela’s capital Caracas fired tear gas and rubber bullets as hundreds of people protested.
The demonstration came days after Venezuelan President Nicolas Maduro hosted opposition leaders for talks to put an end to months of political unrest.
The talks are viewed by some as a monumental task in a country polarised by high levels of poverty.
Months of violent clashes have left at least 30 people dead, hundreds injured and thousands arrested
Venezuelans have been demonstrating against high crime rates, inflation and a lack of basic foodstuffs.
Polls show a drop in support for both Maduro and the opposition since the protests began.
