Gang members are seen inside a cell at Quezaltepeque jail during a media tour in Quezaltepeque, El Salvador, September 4, 2020. Reuters photographer Jose Cabezas: "Members of the MS-13 and Barrio 18 gangs are sworn enemies and historically jails were segregated to prevent violence. However, with an increase in homicides in the midst of the coronavirus pandemic the government changed the policy and stated mixing the prison populations. This cell contains Barrio 18 gang members - you can tell the gang allegiances from the tattoos that cover the men's bodies. Previous times I've visited the prisoners were roaming about the jail but this time the atmosphere was different - the gang members were unusually quiet and controlled. The air smelt musty and heavy from so many people being crammed in together and tired faces watched our every move. I've been covering the gangs for many years and one of the things that always strikes me is how young the gang members are - an older member of the gang might be in his early-twenties. For some it's almost a miracle if they make it to their thirties." REUTERS/Jose Cabezas/File photo SEARCH "POY STORIES 2020" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES.
