Venezuela's Vice President of Security and Food Sovereignty Carlos Osorio attends a ceremony with President Nicolas Maduro at Miraflores Palace in Caracas January 17, 2015. The socialist government of Venezuela launched during the weekend a 30-second spot on state television which invokes Venezuelans to curb nervous "shopping", accusing them of inciting shortages of basic goods in the country. Since early this year, thousands of Venezuelans have crowded outside supermarkets in long queues in search of scarce products such as toilet paper and milk. Picture taken January 17, 2015.
