State oil and electric workers shout slogans during an anti-imperialist rally at Miraflores presidential palace in Caracas, Venezuela, Wednesday, March 18, 2015. The rally was held amid tensions between Venezuela and the U.S. after President Nicolas Maduro this month said Washington is plotting to oust him and ordered the U.S. Embassy in Caracas to slash staffing levels. The U.S. later levied sanctions against seven Venezuelan officials accused of human rights violations. (AP Photo/Ariana Cubillos), APTOPIX
