A National Guardsman and a civilian were killed Thursday in a clash between residents of a Caracas neighborhood and armed men who tried to remove a barricade, Venezuelan officials said. National Assembly President Diosdado Cabello identified the guardsman as 25-year-old Acner Isaac Lopez Lyon, and said that motorcycle taxi driver Jose Gregorio Amaris was also killed while removing debris from the road. Just before the deaths were announced, the country's chief prosecutor said that the death toll from the protests stood at 19 after weeks of student-led protests.
