A leader of a powerful street gang with a tattoo on his head stands in front of a mural of El Salvador's coat of arms painted on the wall of a jail, which houses inmates between the ages of 13 and 25, in Tonacatepeque January 21, 2013. Leaders of the Mara street gangs, who are themselves imprisoned at another location, were granted permission to visit the jail to talk to its inmates about the truce, signed on March 2012 by representatives of the country's two most powerful gangs Mara Salvatrucha and the 18th Street gang (Mara 18), according to local media. The tattoo design features part of El Salvador's coat of arms and the word "dragons". - Reuters/Ulises Rodriguez
