Union leaders and Venezuelan opposition workers march in the capital, Caracas, on May Day to demand labor rights and better wages, clashing with supporters of President Nicolas Maduro's regime. At the parallel but rival demonstration for International Workers' Day, graphic designer Gabriela Ortega attributes the financial burden to sanctions imposed by the United States. "We have made progress compared to previous years, but not completely, because we are facing illegal sanctions," she says. After the May Day celebration, Maduro announced an increase in the minimum wage to 130 USD during a meeting with the oil industry. IMAGES AND SOUNDBITES
