CARACAS, Venezuela (AP) -- President-elect Nicolas Maduro and his opposition rival traded accusations Tuesday over blame for post-election violence that the government said had caused seven deaths and 61 injuries across Venezuela.
Maduro accused the U.S. of fomenting the violence, which appeared less serious than he suggested, while opposition candidate Henrique Capriles accused him of creating a smoke screen to divert attention from the opposition's insistence on a vote-by-vote recount of Sunday's surprisingly close vote.
In Washington, the U.S. State Department backed that demand, saying it would not recognize Maduro without a recount. It was joined by the governments of Panama and Paraguay.
Maduro, the chosen heir of the late Hugo Chavez, spent the day on state TV at various events demonizing Capriles as "a murderer" and coup plotter. He also heaped blame on Washington -- always a popular target of Chavez, the leader Maduro served as foreign minister for six years.
"The (U.S.) embassy has financed and led all these violent acts," Maduro said during a televised meeting at the headquarters of the state oil company.
The countries have been without ambassadors since 2010 and Maduro's rhetoric did not sound designed to encourage the rapprochement that he has told various visiting American politicians he is seeking.
Earlier, Maduro said he would bar an opposition protest march planned for Wednesday in Caracas, saying Capriles was "responsible for the dead we are mourning."
He said he wanted to avoid the kind of violence that preceded a failed April 2002 coup attempt against Chavez that Washington initially recognized. But then Maduro upped the ante, calling on his own supporters to take to the streets Wednesday in the capital.
Capriles subsequently called off the opposition march. It was to have converged on the regime-friendly National Electoral Council, which quickly ratified Maduro's victory Monday.
"Whoever goes out into the street tomorrow is playing the government's game," Capriles said. "The government wants there to be deaths in the country."
According to the electoral council, Maduro won by 262,000 votes out of 14.9 million ballots cast.
Capriles says Chavistas stole the election and provided reporters with some examples:
At 283 polling stations, election monitors were forced to leave before vote counts, some at the point of a gun, he said. At one voting booth in the western state of Trujillo a total of 717 people voted when only 536 were registered, he said.
People marched in various provincial capitals Tuesday to demand a recount, heeding a call by Capriles.
At least one turned violent.
In the capital of Barinas, Chavez's home state, police and National Guard troops fired tear gas and plastic shotgun pellets at protesters marching toward the provincial headquarters of the electoral council. Opposition leaders reported 30 arrests and three minor injuries.
Barinas Gov. Adan Chavez is a brother of Hugo Chavez, the charismatic but divisive leader who succumbed to cancer March 5 after 14 years as president. The opposition blames Chavez for Venezuela's economic disarray, chronic and worsening power outages and rampant crime, including one of the world's highest homicide rates.
Justice Minister Nestor Reverol accused Capriles of numerous crimes, including insurrection and civil disobedience. National Assembly speaker Diosdado Cabello called for a criminal investigation, which he said should include two top Capriles aides: Lara state Gov. Henry Falcon and Carlos Ocariz.
Security analyst Adam Isacson of the Washington Office on Latin America said the rising tension increases chances that the government could arrest opposition leaders, although he wondered whether security forces would comply with a wave of arrest orders.
He said he was more concerned about "mob violence against opposition figures, and perhaps pro-government ones, too."
The Chavistas have long used a loyal criminal justice system to repress the opposition, human rights groups say.
Government officials have kept up a drumbeat of attacks alleging since Monday that Capriles is plotting a coup, including a claim by Maduro that opposition protesters had attacked government health clinics and the house of electoral council President Tibisay Lucena.
Chief prosecutor Luisa Ortega, who announced the death toll, said 135 people had been detained in protests, presumably on Monday, when Capriles' supporters protested in Caracas and other cities, including Barinas, Merida and Maracay.
Ortega did not provide identities for the dead and injured or say where the violence occurred. She said the dead belong to the "working class."
Officials said one death involved a man in the capital supposedly shot by opposition supporters in front of a health clinic. The Associated Press visited the scene and could not establish in interviews with neighbors whether the killing was politically motivated. It did determine, however, that he was not killed near the Cuban-run clinic.
