A Venezuelan opposition lawmaker sought refuge in Argentina's Embassy in Caracas on Thursday, hours after the detention of a key figure in the movement over last week's failed uprising against President Nicolás Maduro.
Richard Blanco is one of 10 National Assembly members charged with treason for supporting opposition leader Juan Guaidó's call for a military revolt on April 30.
"I've come here to sleep because my life is in danger," Blanco told the VPI television station, adding that we would stay only "temporarily."
Blanco sought sanctuary after Edgar Zambrano, the vice-president of Venezuela's opposition-controlled National Assembly, was seized by intelligence agents on Wednesday night.
The EU and several of Venezuela's neighbours protested Zambrano's arrest while the country's Foreign Minister Jorge Arreaza vowed to bring to justice "accomplices to an unconstitutional military uprising,
Venezuela's Supreme Court meanwhile added three more lawmakers to the seven already indicted for treason and conspiracy over their backing of Guaidó's uprising.
Attorney General Tarek William Saab says the two days of clashes that followed left six people dead.
