Supporters and opponents of Venezuela’s leftist government staged dueling rallies Saturday in Caracas and other cities, in the latest wave of demonstrations that have left three people dead. They filled a plaza in Caracas’ Las Mercedes neighborhood and spilled out into nearby streets. Most were students, who have spearheaded nearly two weeks of protests against President Nicolas Maduro. Now, we go out to protest and they kill us,” said university student Isaac Castillo, 27.
