Tens of thousands of Venezuelans have taken to the streets of Caracas for rival marches to mark the 13th anniversary of deadly riots that rocked the country.
The uprising known as the "Caracazo" began February 27, 1989 after the government of then-President Carlos Andres Perez decided to raise fuel and transportation prices. Hundreds of people were killed in several days of rioting.
On Wednesday, supporters of President Hugo Chavez waved flags, carried pro-government banners and displayed the president's photograph while marching to Miraflores, the presidential palace in downtown Caracas.
On a nearby street, anti-Chavez demonstrators headed toward Congress while chanting anti-government slogans and demanding the president resign. There were no reports of confrontations between the two sides.
Mr. Chavez addressed his supporters at Miraflores, where he said his government represents the best interests of all Venezuelans.
The Venezuelan leader is facing growing opposition by business leaders, military officials and unions over his policies. His approval rating has plunged in recent months.
The Confederation of Workers of Venezuelan called for the anti-government march. Petroleum workers are threatening slowdowns if the government continues to make policies seen as attempts to control the industry.
Four military officers have recently called for the resignation of President Chavez. They are concerned over what they say is the manipulation of the armed forces by the president.
Mr. Chavez insists there is no risk of a military coup.
The Bush administration has expressed opposition to any attempt to depose President Chavez before his term is completed. Officials have called upon all parties to respect Venezuela's democratic institutions.
