In Venezuela, at least three people were killed in clashes between police and protesters, as millions of Venezuelans have joined a general strike called by the opposition to cancel elections for a new constituent assembly.
In several cities, police fired tear gas at protesters manning barricades. Police also arrested more than 300 protesters.
In a speech, President Nicolas Maduro vowed some of the strike leaders would be jailed and said the strike was minimal.
He said opposition supporters attacked the headquarters of state TV and burned a kiosk of the government postal service. Violence during four months of anti-government unrest has taken around 100 lives, injured thousands, left hundreds in jail and further damaged an economy in its fourth year of a debilitating decline.
Meanwhile, Colombia, France, Spain, the United States and the European Union have urged the Venezuelan government to cancel the vote for a new constituent assembly on 30 July. But Mr Maduro has rejected the calls. The opposition is boycotting the vote. U.S. President Donald Trump also threatened economic sanctions if the July 30 vote goes ahead.
