Venezuelan police fired tear gas and turned water cannons on stone-throwing protesters on Saturday to stop them blocking a Caracas highway in a fourth day of sporadic unrest against President Nicolas Maduro's government.
The latest trouble flared as night fell, after thousands of Maduro supporters had earlier flooded the center of the capital to call for peace and make a show of political strength after this week's deadly violence during street protests.
Three people were shot dead on Wednesday in the worst violence since Maduro's disputed election last year.
The 51-year-old successor to Hugo Chavez has faced two weeks of mainly small protests led by students and hardline opposition leaders complaining about Venezuela's rampant crime, shortages of basic products, and alleged repression of political rivals.
