CARACAS, Feb. 17 (Xinhua) -- Venezuelan Vice President Jorge Arreaza on Monday warned the country's opposition and its followers against the "fascist" elements in the ring-wing groups, which he alleged have orchestrated protest violence that claimed three lives over the past few days.

　　"The people who follow the opposition should not be manipulated by the plans and hatred of the fascist sector of the right-wing groups," Arreaza wrote in his Twitter account. "I hope the opposition leaders that accepted the dialogue proposed by President Nicolas Maduro will not be manipulated again by the fascists."

　　While trumpeting the country's Constitution allows the protests within the legal frame, the vice president warned it is necessary for people to act with awareness to strengthen national unity.

　　President Nicolas Maduro has announced a decision to expel three U.S. Embassy officials, accusing them of conspiring against his government.

　　In a recent interview with a local TV service, Ernesto Villegas, the minister of Urban Transformation of Caracas, the Venezuelan capital, also alleged that the recent street violence in Caracas and other states are part of a systematic plan of the U.S. government to overthrow the Bolivarian Revolution, a leftist social movement and political process now led by Maduro.

　　"The owners of this circus are in Washington," he said, urging the Venezuelan people to support peace building process in the country.

　　The Parliament of the Common Market of the South (Mercosur), an economic integration entity, announced Monday that it would send an observation mission to Venezuela to help address its internal conflict. "Venezuelans should resolve their problems without any foreign intervention, toward the building of the South American unity," it said.

　　The unrest in Venezuela, ignited by the anti-government protests, killed three and injured 70 in the past days.
