Members of the National Guard stand guard in the streets of Venezuela's third city, Valencia, on August 6, 2017, a day after a new assembly with supreme powers and loyal to President Nicolas Maduro started functioning in the country.
In the video posted online earlier, allegedly at an army base used by the National Bolivarian Armed Forces in Valencia, a man presenting himself as an army captain declared a "legitimate rebellion... to reject the murderous tyranny of Nicolas Maduro" and demanded a transitional government and "free elections." After the video surfaced, military chiefs said troops had put down the "terrorist" attack.
