A billboard with an image of the late Venezuelan President Hugo Chavez is seen outside a refinery in Ciudad Ojeda, in the state of Zulia, Venezuela, March 20, 2015. Venezuela’s national crime pandemic – the United Nations says the country has the world’s second-highest murder rate after Honduras – is a growing headache for the oil industry, which accounts for nearly all of the country’s export revenues. Hold-ups and thefts in the sector are on the rise, taking a toll on output, according to interviews with around 40 people, including oil workers, union leaders, foreign executives, opposition politicians, scrap dealers, and people who live near oil installations. The sign reads, “Welcome, tank farm of Tasajera refinery”. To match Insight VENEZUELA-OIL/CRIME Picture taken on March 20, 2015. REUTERS/Isaac Urrutia
