A militia member (L) holds a national Venezuelan flag next to a worker of the national electricity company (CORPOELEC), as they pose for the media during a defensive military exercise in a thermoelectric power plant in La Fria, at the state of Tachira March 14, 2015. Venezuela on Saturday staged a military exercise to counter an alleged U.S. threat, deploying soldiers and partisans across the country to march, man shoulder-fired missiles and defend an oil refinery from a simulated attack.
