Agents of Venezuela's domestic intelligence service have arrested the opposition mayor of a western city that has been a crucible of anti-government resistance and which spawned the current wave of protests.
San Cristobal Mayor Daniel Ceballos, who a top aide said was arrested in a Caracas hotel, became the second opposition leader jailed by Venezuela's socialist-led government since the unrest began last month. Opposition leader Leopoldo Lopez is being held on charges of arson and conspiracy.
Ceballos, who was in Caracas for a meeting of opposition mayors, had been outspoken in his criticism of what he called repression by security forces in his city. His aide, Ronni Pavolini, said agents from the Bolivarian National Intelligence Service, known by its Spanish initials SEBIN, arrested Ceballos.
"They took him out of the hotel in Caracas and took him to Helicoide (SEBIN headquarters)," Pavolini told The Associated Press.
Interior and Justice Minister Miguel Rodriguez Torres confirmed the arrest later on state television. "This is an act of justice for a mayor who not only did not meet his obligations as required by law and the constitution, but also facilitated and supported all the irrational violence in San Cristobal."
The anti-government protests that have shaken Venezuela for more than a month began in early February with students in San Cristobal, an opposition stronghold along the border with Colombia. Since then it has seen intense clashes between authorities and protesters frustrated by soaring inflation, rampant violent crime and shortages of basic items such as cooking oil and toilet paper.
Late Wednesday, the federal prosecutor's office said that, according to preliminary information, National Guardsman Jhon Rafael Castillo Castillo, 23, was killed while breaking up protests near a local university in San Cristobal. That would be the fifth National Guardsmen killed during the protests.
Meanwhile, about 25 kilometres from San Cristobal, National Guardsmen firing plastic shotgun pellets and tear gas wounded at least 16 people in the town of Rubio as they cleared barricades that had been up for weeks, local officials said.
Rubio residents reported an intense effort by the National Guard to clear protesters' barricades that had sealed off neighbourhoods.
"The situation is terrible here," Francisco Rincon, vice president of the Rubio municipal council, told The Associated Press. He said soldiers with rifles were on the street corners. He said he had counted 16 wounded, four of them by bullets.
Rincon, who is a member of the opposition Popular Will party, said their supporters had protested peacefully in the morning before being dispersed by tear gas and plastic buckshot by National Guardsmen and pro-government civilians.
In Caracas, officials said a municipal worker was shot and killed while removing a street barricade in a middle-class neighbourhood. His death raised to 28 the official toll from more than a month's worth of protests.
The federal prosecutor's office said Francisco Alcides Madrid Rosendo, 32, was shot multiple times around 10pm local time while he and others were taking down a barricade in the Montalban neighbourhood in Caracas' western section.
Pro-government Caracas Mayor Jorge Rodriguez through his Twitter account blamed unnamed "terrorists" for the killing, but provided no other details.
Besides authorities arresting Ceballos and Lopez, Venezuela's National Assembly on Tuesday voted to start a process to strip opposition lawmaker Maria Corina Machado of her immunity so they could eventually bring charges against her for allegedly trying to destabilize the government.
Machado was expected to speak on Friday at a meeting of the Organisation of American States in Washington about the situation in Venezuela. Because the Venezuelan government controls the country's seat, Panama has offered Machado its seat to make her presentation to the regional body.
Venezuela accuses her of civil disobedience and trying to destabilize the government.
Machado told a reporter from The Associated Press who was on the same flight to Miami on Wednesday that she was "very worried" about the effort to bring criminal charges against her.
"It's fundamental that the world understand what's happening in our country," she said of her upcoming appearance before the OAS.
The body earlier this month approved a declaration supporting President Nicolas Maduro's efforts to start a dialogue with the political opposition. Panama, the United States and Canada voted against it.
