Sellers withdraw their produce as police investigators secure a crime scene at La Tiendona market in San Salvador, July 2, 2015. Miguel Angel Acevedo was killed by suspected gang members while he was selling potatoes at La Tiendona market, one of the most violent places in San Salvador, according to local media. In El Salvador the number of homicides surged 70 percent last year, making the central American nation among the most violent countries in the world. Violence and murders have risen steadily since a 2012 truce between the two main street gangs began to fall apart. Months of reporting show killings in the suburbs of the capital, San Salvador, where powerful gangs known as maras control entire neighbourhoods.
